2008-05-26 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_win32.c: Replace custom Win32 memory api with generic
POSIX one. No apparent value to use of GlobalAlloc() in the modern
age. http://bugzilla.maptools.org/show_bug.cgi?id=1885
* libtiff/tiffconf.vc.h: Added JBIG_SUPPORT and MDI_SUPPORT items
in windows version (care of Edward Lam).
