[PATCH] version 0001 Port to 12 other Platforms.

This patch adds support to compile and run git on 12 additional platforms. The platforms are based on UNIX Systems Labs (USL)/Novell/SYS V code base. The most common are Novell UnixWare 2.X.X, SCO UnixWare 7.X.X, OpenServer 5.0.X, OpenServer 6.0.X, and SCO pre OSR 5 platforms.

This is from

The problem is that git source has blocked some typedefs by excluding certain <sys/types.h> content.

Looking at the the various platform header, I see around line 450

     && !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)

which hides u_short and other typedefs that other header files on these platforms dependon. With _XOPEN_SOURCE defined, sources that include system header files that depend on the typedefs such as u_short cannot be compiled on these platforms.

They all lead back to about line 66 in git-compat-util.h

I had to make the following changes

ned(_M_UNIX)
 #define _XOPEN_SOURCE 600 /* glibc2 and AIX 5.3L need 500, OpenBSD needs 600 fo
r S_ISLNK() */
 #define _XOPEN_SOURCE_EXTENDED 1 /* AIX 5.3L needs this */
 #endif

The _XOPEN_SOURCE hides many typedefs. __USLC__ indicates UNIX System Labs Corperation (USLC), or a Novell-derived compiler and/or some SysV based OS's.

__M_UNIX indicates XENIX/SCO UNIX/OpenServer 5.0.7 and prior releases of the SCO OS's. It is used just like Apple and BSD, both of these shouldn't have _XOPEN_SOURCE defined.

This is with suggestions and modifications from
