Systems/environments without glibc (such as CygWin), and as a consequence whithout the __GLIBC_PREREQ() macro, fail to build with the following error message:

    CC git.o
In file included from builtin.h:4,
                 from git.c:1:
git-compat-util.h:187:48: missing binary operator before token "("

Here is a relevant comment from my Linux box features.h:

/* Convenience macros to test the versions of glibc and gcc.
   Use them like this:
   #if __GNUC_PREREQ (2,8)
   ... code requiring gcc 2.8 or later ...
   #endif
   Note - they won't work for gcc1 or glibc1, since the _MINOR macros
   were not defined then.  */

My CygWin gcc version is:

$ gcc -dumpversion 3.4.4

This applies to next
