No, there's no difference.  The inclusion evidence is like this:

  # 1 "../lib/limits.h" 1 3

Do you see such a line in the preprocessed file?  If you do, then does
it include this line further down:

  #define LLONG_WIDTH _GL_INTEGER_WIDTH (LLONG_MIN, LLONG_MAX)

I then searched back for _GNU_SOURCE and saw this:

  #define _GNU_SOURCE 1

and a little ways above it I saw this:

  # 1583 "./config.h"

Do you see these?

Etc. etc. -- just go back and look whether the file inclusion I
described happens on your system.

If you cannot figure this out, send the preprocessed source of
w32proc.c, sure.  I will take a look.

Thanks.
