I suggest using /MD or /MDd rather than /MLd. For some programs it may not make
any difference, but for real applications /MD (use DLL run-time library) is the
only practical option. If you link against a static version of the run-time lib
with /ML or /MT, then the executable and each DLL has its own version of a
memory manager, and if you pass allocated memory across the boundaries (e.g.
returning a string by value), then the debug heap memory manager complains.
With /MD, all pieces share a common memory manager. There are ways to avoid the
problem, but it gets complicated. See article Q94248 in the MS knowledge base.

Doesn't CL.EXE send back a return code if the compilation doesn't succeed? It
used to be possible to write batch files that checked for errorlevel, IIRC.
