Modified files:
	cm3/m3-sys/m3linker/src/: MxGen.m3 

Log message:
	fix _m3main.c so it can be compiled with a C++ compiler in place of a C compiler
	NOTE: We require at least an ANSI C compiler.
	I have fairly recently used systems with a K&R C compiler
	but no ANSI C compiler (Irix accidentally-looking-bundled compiler
	and HPUX/hppa bundled compiler that exists to compile data initialization
	and relink kernel).
	I'll revise this if/when I'm back at such a system.
	I doubt anyone else cares.
	(That is, _m3main.c should be valid K&R C, valid ANSI C, and valid C++.)
