stdio-h: Work around [v][f]printf bugs in mingw with msvcrt. Reported by 松延 英樹 <maznobu@gmail.com> in <https://github.com/mlocati/gettext-iconv-windows/issues/52>. * lib/stdio.in.h (gl_consolesafe_fprintf, gl_consolesafe_printf, gl_consolesafe_vfprintf, gl_consolesafe_vprintf): New declarations. (fprintf): When msvcrt is in use, use gl_consolesafe_fprintf. (printf): When msvcrt is in use, use gl_consolesafe_printf. (vfprintf): When msvcrt is in use, use gl_consolesafe_vfprintf. (vprintf): When msvcrt is in use, use gl_consolesafe_vprintf. * lib/stdio-consolesafe.c: Include fseterr.h. (gl_consolesafe_fprintf, gl_consolesafe_printf, gl_consolesafe_vfprintf, gl_consolesafe_vprintf): New functions. * lib/stdio-write.c (vfprintf): When msvcrt is in use, use gl_consolesafe_vfprintf. * modules/stdio-h (Depends-on): Add fseterr. * doc/posix-functions/fprintf.texi: Document the mingw bug. * doc/posix-functions/printf.texi: Likewise. * doc/posix-functions/vfprintf.texi: Likewise. * doc/posix-functions/vprintf.texi: Likewise.
