Use of undefined macro in libc-config.h

[Tim Rühsen]

MinGW tells me


In file included from ../lib/glob.h:24:0,
                 from options.c:50:
../lib/libc-config.h:49:65: warning: "__GNUC_MINOR" is not defined [-Wundef]
 #  define __GNUC_PREREQ(maj, min) ((maj) < __GNUC__ + ((min) <=
__GNUC_MINOR))
                                                                 ^
../lib/cdefs.h:41:6: note: in expansion of macro '__GNUC_PREREQ'
 # if __GNUC_PREREQ (4, 6) && !defined _LIBC
      ^~~~~~~~~~~~~

The fix seems trivial, but I am unsure *why* __GNUC_MINOR isn't defined.
I would expect that from any gcc derivative (x86_64-w64-mingw32-gcc / -cpp).

What do you say ?

With Best Regards, Tim
