Could you please describe the problem in more detail?  What exactly
causes search-forward to fail, and how is the case of MSVC different
from other compilers?  In other words, what makes this case fail when
other compilers don't?

It's not documented because the code which uses this is not meant for
the Windows version of Emacs, it's for the MS-DOS version, where
msdos-shells are set up at startup.  Could you please suggest a change
that would do similar things for MS-Windows?
