adaint.h, adaint.c (__gnat_rmdir): New routine.

2009-04-16  Pascal Obry  <obry@adacore.com>

	* adaint.h, adaint.c (__gnat_rmdir): New routine.
	Simple wrapper routines used to convert to proper encoding on
	Windows.

	* s-crtl.ads: Use __gnat_rmdir instead of direct call to the C library.

	* g-dirope.adb (Remove_Dir): Fix a bug, the root directory was removed
	twice.
