[M3devel] More testing needed for m3back, was: RE: m3back/longint/atomics

Fri Feb 19 04:07:36 CET 2010

Hi all:
great news to hear about a release coming soon, but how about testing NT386GNU or derivatives of it, would be hard to set up (I might try a friend's machine).
As I understood that was a great port to new Modula-3 programmers coming into the M3 world from win world. This doesn't have the all packages but is this a must to give have a check to release this port?
Any news from cvsup ticket #1080 https://projects.elego.de/cm3/ticket/1080 ?
Is there any chance to bring those platforms in final release? 
Any difficulties to start trying that?
Thanks in advance
