Subject: [Ada] Fix bug in GNAT.OS_Lib.Locate_Regular_File

Tested on i686-linux, committed on trunk

This patch fixes a bug that caused unallocated memory to be addressed
when calling GNAT.OS_Lib.Locate_Regular_File with an empty string as
File_Name, potentially causing undetermined return results at best, or,
at worst, segmentation violations.

2005-12-05  Nicolas Setton  <setton@adacore.com>

	* adaint.c (__gnat_locate_regular_file): Return immediately if
	file_name is empty.
