[M3devel] config init problem

[Olaf Wagner]

In MxConfig.m3 quake runtime exception were ignored and thrown away
in EvalConfig. Writing them to stderr, we get the following output
for a simple cm3.cfg file:

% cat ~/cm3-rc3/bin/cm3.cfg

%INSTALL_ROOT = "/ad0e/home/wagner/cm3-rc3"
INSTALL_ROOT = path() & SL & ".."

include(path() & "/config/FreeBSD4")

   target:

SL gets defined in M3Build.m3 in cm3, along with all the other
builtins that the compiler may use (and the config file author).
Of course MxConfig in package m3quake does not know about these,
as it creates its own quake machine on the fly.

So configuration evaluation won't work in general currently,
unless only standard quake functions and definitions are used.

Any ideas?
