Hi Phil--

    I don't know about the version of rexxsaa.h that comes with Borland
C++ compilers, but there were bugs in early versions of rexxsaa.h that
came with the Warp Toolkit distributed with the first few DevCon volumes
issued after Warp GA was released.  (David Noon said the bugs were
inserted when the separate include files for C and C++ were combined.)
The bugs were swatted in newer versions (filedate 5/13/95, and later).

    I patched the early Warp rexxsaa.h files with my text-mode text
editor (rather than mucking up my source code) by inserting the APIENTRY
where needed.  If I remember correctly, there were four definitions in
that file that needed to be patched.

    AFAIK, the "C" version of rexxsaa.h in Toolkit versions 2.x, as
distributed with DevCon since the beginning, were bug-free.

    Regards,

          --Murray
