The MSVC compiler also has no <strings.h>. Here's a fix to avoid to
include a nonexistent header file.
2011-09-11 Bruno Haible <address@hidden>
strings: Don't assume <strings.h> exists.
* lib/strings.in.h: Include <strings.h> only if HAVE_STRINGS_H is 1.
* m4/strings_h.m4 (gl_HEADER_STRINGS_H_BODY): Set HAVE_STRINGS_H.
* modules/strings (Makefile.am): Substitute HAVE_STRINGS_H.
* doc/posix-headers/strings.texi: Mention the MSVC problem.
