[M3devel] more cm3cg on Raspberry Pi

Tue Oct 22 18:28:02 CEST 2013

Well I deleted ARMEL_LINUX/m3cc for good measure and still...

  assemble => 1
assembler failed assembling: TickPortable.ms

(etc.)

I'm really quite happy to use the C-generating compiler but need to make
sure it is working right.  Although of course it would be a bonus to have
a "native" compiler, too.  I was hoping to do performance comparisons
but can of course do those on FreeBSD4 or some x86-based Linux too.
Or have you already done them?
