The csharp-test.exe program is compiled (by Mono's compiler) from a trivial
program with an empty Main method. If an 'ilrun' program cannot execute this,
it either has a severe binary incompatibility with mono or is unusable for
anything. IMO this should be reported as bugs in the Debian pnet packages.

I've verified that on x86, the versions 0.6.4, 0.6.10, 0.7.2, 0.8.1 (built
from source, not from Debian) all execute the csharp-test.exe program fine.

You can avoid the hang in future configure runs by using the option
--enable-csharp=mono.
