Modified files:
	cm3/m3-tools/m3tk/src/fe/: M3CGo.m3 

Log message:
	Fix a bug in m3tk that was uncovered by previous fix to LONGINT
	literal checking, causing NIL deref crashes.  M3Go.CompileUnit
	was failing to call M3Error.SetCu, leaving no current unit for
	error messages.
	
	There are other mysteries here, but this cures the crash and
	reproduces previous output for at least one case.
