Unfortunately, the last part does not seem to be true. There are
two separate problems.

First, the two invocations of pkg-config in make.sh means that the arguments
that get passed to mmc will be different on my system than on yours,
and in fact on mine, I get just error messages from them. I don't even know
what purpose they are supposed to serve, given that the compiler bug you report
should prevent mmc from ever getting to the point where it compiles C code.

Second, iosupp.m imports a module named unicode, which is not
in bug.tar.gz.

Zoltan.
