It is not "for convenience". It is for correctness.

20 years ago it was usual that you had to #include <sys/types.h>
before <regex.h> or similar. This was rectified in the standards
and then also in the implementations. The standard behaviour for
#include files nowadays is:
  1) Every header file can be #included by itself.
  2) When several header files are #included, the order does not
     matter.

Platforms that don't satisfy this are buggy.

mingw-w64 is still in alpha state, as can be seen from the URL
you cited:
  "The current state: It is already possible to generate
   applications using these headers, libs and runtime together
   with gcc-4.4 and up :-) There might be bugs here and there"

OK, let them fix the bugs. There is no need for gnulib to work
around bugs in platforms that are in not widespread use and are in
active development.

Can you report it to the mingw-w64 people, please?
