Update mapm to 4.9.5a.
Based on PR#43736 by Kamel Derouiche.

V 4.9.5 -  Dec 10, 2007    Updated software license, allowing distribution
  of modified source code.

  The actual library source code is identical to
  version 4.9.2 (except the obvious library version
  identifier, and Digital Mars #ifdef).

  Added support for the Digital Mars Compiler.

  Added build script for Intel Linux Compiler.

V 4.9.5a - Feb 21, 2010    Updated authors email address.

  Note that there are no changes to the library
  source code - so the library will still identify
  itself as "4.9.5".

  Added Makefile for Microsoft Visual Studio 2005.

  Added another Makefile for MAC OSX (for 10.6).
