Hi Stefan,

I'd see if you could build gcc (C and C++) on Arch and find a version
which builds cleanly.  Good candidates are gcc-5.4.0, gcc-6.4.0 or
gcc-trunc as there are Modula-2 branches for these releases.  At that
point I'd enable Modula-2.  From the above error - I think it looks as
it it would not build a C/C++ compiler,

regards,
Gaius
