I don't like your chances of using VC++ to build Portable.NET.  Pnet makes 
heavy use of shell scripts, bison, flex, and treecc to build source files on 
the fly to compile with gcc.  Integrating these meta-conversion tools into 
VC++ will be extremely difficult.

If you wish to submit patches for VC++, then we'd welcome them, but it isn't a 
high priority for us to work around broken MS compilers.

Eventually we will be moving pnet to build with dynamic libraries.  When we 
do, "dlltool" will take care of this detail.

The native threads are used instead of pthreads under Win32, because pthreads 
implementations are unreliable in a Win32 environment.  Also, libgc uses 
Win32 threads and so pnet has to use the same package to match up with libgc.

-lwsock32 is necessary to get the socket routines.  Network support (e.g. 
System.Net) won't be possible without it.

You can build without libffi if you like by using "./configure 
--without-libffi", but you lose access to PInvoke.  Building without libgc is 
not recommended: it implements the garbage collector.  You can build without, 
but you won't be able to run anything except simple "Hello World" examples.

That's strange.  I haven't seen that one before, so I'm not sure what to 
recommend.

Log these "make check" errors in Savannah and I'll try to find the time to 
look into them soon.
