Well, another possibility is to just drop the -cc flag, because "gcc -E -x c"
is the default already (why is it set to cat anyway?).

Yet another possibility would be to leave it "cat" and change mig to not
have -undef in the cppflags variable, but in default_cpp:

default_cpp="gcc -E -x c -undef"
cppflags=""

A third possibility is to drop the -undef again, because it does not work
anyway (i386 is still defined to 1 in gcc).  Roland, you did this change,
what do you think?

Thanks,
Marcus
