Re: MinGW compilation errors with Gnulib wchar.h and wctype.h

The usual method is to alter the gnulib .h file so that it merely include_next's 
the system .h file when it detects that its partial inclusion is desired. 
Something like this:

#ifdef __need_FILE
# @INCLUDE_NEXT@ @NEXT_STDIO_H@
#elif !defined _GL_STDIO_H
# @INCLUDE_NEXT@ @NEXT_STDIO_H@
# define _GL_STDIO_H
  /* our own fixups */
#endif

It often gets more complicated than this (see lib/stdio.in.h), but that's the 
basic idea.

It would be nicer if MinGW didn't have the problem in question. They could do 
that by altering their include-file practices.
