2009-07-13  Thomas Quinot  <quinot@adacore.com>

	* g-socthi-vxworks.adb (C_Sendto): VxWorks does not support the
	standard sendto(2) interface for connected sockets (passing a null
	destination address). Use send(2) instead for that case.

2009-07-13  Pascal Obry  <obry@adacore.com>

	* adaint.c: Fix __gnat_stat() with Win32 UNC paths.
