[fyi] Add gdb_dirent.h and use

[Andrew Cagney <ac131313 at cygnus dot com>]

FYI,

This replaces any includes of <sys/dir.h> and <dirent.h> with
"gdb_dirent.h".  As IanT noted on the binutils list:

> I believe that on some systems you must include <sys/dir.h> before
> including <sys/user.h>.  I'm not completly certain about that, though.

Thu May 25 15:22:12 2000  Andrew Cagney  <cagney@b1.cygnus.com>

	* configure.in (AC_CHECK_HEADERS): Check for <dirent.h>,
 	<sys/ndir.h>, <sys/dir.h> and <ndir.h>.
	* config.in, configure: Re-generate.	
	* gdb_dirent.h: New file

	* infptrace.c: Include "gdb_dirent.h" instead of <sys/dir.h>.
	* core-aout.c: Ditto.
	* procfs.c: Include "gdb_dirent.h" instead of <dirent.h>.
