[M3devel] replace build system??

[Jay K]

We need to understand if and how well Modula-3 fits in the traditional and widespread C build infrastructure.

Does/can it retain its build speed if you invoke cm3 per .i3 and per .m3 file?
Does/can it retain its incrementality?

Or do we really need to be more of the "driver" and do a lot of stuff at the lib/link level?
