	Add support for Win32 native encoding for delete/rename routines.
	
	* adaint.c (__gnat_unlink): New routine.
	(__gnat_rename): New routine.
	Simple wrapper routines used to convert to proper encoding on
	Windows.

	* s-os_lib.adb: Use __gnat_unlink and __gnat_rename instead of direct
	call to the C library.

	* g-sercom-mingw.adb, s-win32.ads: Update Win32 binding.

2009-04-15  Robert Dewar  <dewar@adacore.com>

	* s-tassta.adb: Minor reformatting
