Other compilers are presently not supported. Most notably, some people have tried to compile using VAC 3.6.5 and ran into problems.
I am still using the Warp 3 toolkit, mostly because if XWP is built
using a newer toolkit, it will not start on Warp 3. Besides, it appears that
the SOM compiler and nmake from the Warp 4.5 toolkit have some
problems, according to some reports I got.
As said above, newer nmake's appear to have problems with
XWorkplace's makefiles, mostly with invoking the SOM compiler. I am using
nmake 3, which comes with either the Warp 3 toolkit or VAC 3.

you will need the full PMPRINTF package by Dennis Bareis.
