Changelog:
2012-11-21
# Changes and additions
* On Windows, process now returns real process ids as in UNIX, not Windows process handles.
* The cgi.lsp module now handles multiform data in POST requests.

# Bug fixes
* Memory overrun of invalid UTF8 strings now causes an error message "invalid UTF8 string".
* The function ref did sometimes not handle correctly multiple, nested matching expressions.
* The float function did sometimes not work correctly when used on list members.
* OpenBSD did not load .init.lsp.

# Compatibility with previous versions
* This version is compatible with previous versions in the 10.4 series of newLISP.
