[M3devel] compile problem on LINUXLIBC6

Sat Jan 22 20:44:58 CET 2011

libcpp is part of any gcc frontend/backend. I have reduced it significantly, but it is still there.

Maybe it was caused by this:

  * m3-sys/m3cc/src/clean_marker.txt:

  system.h: all systems have:
   stddef.h
   limits.h
   abort
   realloc
...

anyway, I made a change that should resolve this. Let me know.
I'll try to keep up with Hudson, but things have changed
semi-permanently very significantly for me..less time on Modula-3 probably forever now...
(I'll still try to fix the jumpbuf over-use and maybe stack-walker absence...)
