2007-09-26 Olivier Hainque <hainque@adacore.com>

	* adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
	#include <utime.h> and #define GCC_RESOURCE_H before
	#include <sys/wait.h>.
	Add more protections in __gnat_translate_vms.

	* expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
	#include <sys/wait.h>.
