	* makegpr.adb (Compile): Put the compiling switches (in package
	Compiler and on the command line) immediately after "-c", instead of
	at the end of the command line invocation of the compiler, when
	compiling a non-Ada file.
	(Build_Global_Archive): When there is no need to rebuild the archive,
	set Global_Archive_Exists, so that the archive is passed to the linker
	if one is needed.
