As an example, if\n tab completion in the user's shell appends trailing slashes, the\n command './configure --prefix=/usr/' will still result in an\n expanded libdir value of /usr/lib, not /usr//lib.\n\n** `configure --help=recursive' now works in read-only trees and from\n unconfigured build trees.\n\n** If precious variables differ only in whitespace, then the cache consistency\n check warns instead of fails, and reuses the old value.\n\n** AT_BANNER is now documented.\n\n** AT_SETUP now handles macro expansions properly when calculating line\n length.\n\n** Autotest now determines $srcdir correctly.\n\n** Testsuites built by autotest now accept a -C/--directory=DIR option\n to adjust the working directory prior to creating files.\n\n** Autoconf now requires GNU M4 1.4.5 or later. Earlier versions of M4 have\n a bug in macro tracing that interferes with the interaction between\n Autoconf and Automake. GNU M4 1.4.11 or later is recommended. The\n configure search for a working M4 is improved.\n\n** For portability with the eventual M4 2.0, macros should no longer use\n anything larger than $9 to refer to arguments.\n\n** Documentation for m4sugar is improved.\n\n \ - The following macros were previously available as undocumented\n interfaces; the macros are now documented as stable interfaces.\n\n __oline__ m4_assert \ m4_bmatch m4_bpatsubsts m4_car m4_case\n m4_cdr m4_default m4_divert_once \ m4_divert_pop m4_divert_push\n m4_divert_text m4_do m4_errprintn m4_fatal \ m4_flatten\n m4_ifndef m4_ifset m4_ifval m4_ifvaln m4_location\n m4_n \ m4_shiftn m4_strip m4_warn\n\n - The following macros were previously available as undocumented\n interfaces, but had bug fixes or semantic changes as part of this\n release. Packages that relied on the undocumented behavior\n should be analyzed to make sure they will still work with the\n new documented behavior.\n\n \ m4_cmp m4_list_cmp m4_join m4_map m4_map_sep m4_sign\n m4_text_box \ m4_text_wrap m4_version_compare\n\n - The m4_wrap macro used to have unspecified order, but now\n guarantees FIFO order. m4_wrap_lifo was added to guarantee LIFO\n order.\n\n - Packages using the undocumented m4sugar macro m4_PACKAGE_VERSION\n \ should consider using the new AC_AUTOCONF_VERSION instead.\n\n - m4sugar macros that are not documented in the manual are still\n deemed experimental, and should not be used outside of Autoconf.\n\n** The m4sugar macros m4_append and m4_append_uniq, first documented in\n 2.60, have been fixed to treat both the string and the separator\n arguments consistently with regards to quoting. \ Prior to this fix,\n m4_append_uniq could mistakenly duplicate entries if the expansion\n of the separator resulted in a different string (for example, if it\n contained quotes, a comma, or a macro name). However, it means\n that programs previously using\n m4_append([name], [string], [[, ]])\n are now using a four-character separator instead of the intended\n comma and space. \ If you need portability to earlier versions of\n Autoconf, you can insert the following snippet after AC_INIT but\n before any other macro expansions, to enforce the new semantics:\n m4_pushdef([m4_append], [m4_define([$1],\n\t \ m4_ifdef([$1], [m4_defn([$1])[$3]])[$2])])\n Additionally, m4_append_uniq now takes optional parameters that can\n be used to take action depending on whether anything was appended,\n and warns if a non-empty separator occurs within the string being\n appended, since that can lead to duplicates.\n\n** The following m4sugar macros are new:\n m4_append_uniq_w m4_apply m4_combine m4_cond m4_count\n \ m4_dquote_elt m4_echo m4_expand m4_ignore m4_make_list m4_max\n m4_min \ m4_newline m4_shift2 m4_shift3 m4_unquote m4_wrap_lifo\n\n** Warnings are now generated by default when an installer invokes\n 'configure' with an unknown --enable-* or --with-* option.\n These warnings can be disabled with the new AC_DISABLE_OPTION_CHECKING\n macro, or by invoking 'configure' with --disable-option-checking.\n\n** Existing obsolete macros\n The documentation for the following macros is adjusted to make it\n more clear that they have previously been marked obsolete, as their\n \ functionality can be accomplished by other macros. We have no\n current plans to remove them from Autoconf.\n\n AC_ENABLE AC_STRUCT_ST_BLKSIZE AC_STRUCT_ST_RDEV \ AC_WITH\n\n** Newly obsolete macros\n The following macros have been marked obsolete, as they only\n perform a subset of AC_USE_SYSTEM_EXTENSIONS. We have no current\n plans to remove them.\n\n AC_AIX AC_GNU_SOURCE AC_ISC_POSIX \ AC_MINIX\n\n** AC_C_LONG_DOUBLE is obsolescent.\n The documentation now says that AC_C_LONG_DOUBLE is obsolescent: it\n tests for problems that are so old that it is no longer of\n practical importance on current systems. New programs need not use\n AC_C_LONG_DOUBLE. We have no current plans to remove it.\n\n** AC_DIAGNOSE, AC_WARNING, and AC_FATAL are obsolescent.\n The documentation now favors the use of M4sugar macros m4_warn and\n m4_fatal, since the naming makes it more obvious that the\n diagnostics are associated with M4 expansion (ie. when running\n `autoconf'), and offers less confusion with the AC_MSG_ERROR,\n \ AC_MSG_FAILURE, and AC_MSG_WARN macros which manage diagnostics\n when running `configure'. We have no current plans to remove these\n macros.\n\n* Major changes in Autoconf 2.61a (2006-12-11)\n\n** AC_FUNC_FSEEKO was broken in 2.61; it didn't make fseeko and ftello visible\n on many platforms. This has been fixed.\n\n** AC_FUNC_SETVBUF_REVERSED is now obsolete. It is still defined for backward\n compatibility but it does nothing. The macro was already\n obsolescent, as the last systems to have the problem were those\n based on SVR2, which became obsolete in 1987. The macro had bugs\n on some modern systems and could no longer be maintained reliably\n due to lack of ancient systems to test it on.\n\n** config.status now uses awk instead of sed for most substitutions, for speed.\n\n \ - As a side effect multi-line values of substituted variables no\n longer have a small limit in total size, though for portability\n each line should not exceed the POSIX length limit for text lines.\n\n - It is now documented that Makefile.in should not contain\n overlapping variable occurrences, e.g., @VAR1@VAR2@.\n Autoconf's behavior was always iffy in such cases, and the\n \ awk implementation has changed the behavior.\n\n** Many uses of 'echo' have been rewritten so that Autoconf-generated\n scripts have fewer problems with strings or file names containing\n embedded special characters such as backslash or leading \"-\". This\n was implemented by using `printf '%s\\n' \"$foo\"' instead of `echo\n \"$foo\"' when printf works. Due to the implementation technique\n \ used, Autoconf-generated scripts now run considerably more slowly\n on ancient implementations lacking printf. However, this should\n not be a problem, since Autoconf-generated scripts in practice\n invariably find a more-modern shell these days.\n" module: pkgsrc subject: 'CVS commit: pkgsrc/devel/autoconf' unixtime: '1208127008' user: wiz
