	* bindgen.adb (Gen_Adainit_Ada): If the main program is a CIL function,
	then use __gnat_set_exit_status to report the returned status code.

	* comperr.adb (Compiler_Abort): Convert most bug boxes into clean error
	messages on .NET, since some constructs of the language are not
	properly supported.

	* gnatlink.adb (Gnatlink): In case the command line is too long for the
	.NET linker, gnatlink now concatenate all .il files and pass this to
	ilasm.
