:-) Well, i tested on platforms where these invocations
miserably fail because there was no matching C-compiler
available and then they give long obnoxious tracebacks from
within distutils somewhere.

OK, from the containing "build_cfunc" function i didn't guess
that the call to t.ccompile() was supposed to be a test by itself.
I guess that either the Genc() part should be called separatedly
or we should have our distutils invocations fail more cleanly
and extend "skip_on_error" to require specifying an explicit
Exception class. then the above could turn into
which - hopefully - GenC() does not raise :-)
