?what?

I think what the original poster had in mind was that the include path is
passed in the argument list for p0.exe and if the path is too long cl.exe
can't exec p0.exe because the argument list is longer than DOS allows
(128 characters ?).  I have had the same problem when trying to use "many"
-Ddefines on the command line.  The argument list was short enough for
cl.exe to accept but the augmented list passed to p0.exe was too long.

As far as I know, there is no way around the 128 character argument list
limit.  It's intrinsic to DOS.  I wish they'd fix it.
