buidling emacs 21.2 on solaris 7 or later

Hello.  I have recently run into a new problem building emacs 21.2
on solaris 7, 8, 9.  The problem may be Sun's fault, but I thought
I would run it past you first.

I had successfully built emacs 21.2 on solaris 7 twice in 2002.
In December, I tried to build it again (same computer, same version
of gcc).  But the build failed in the lwlib directory (see below).
I traced this new problem to a change in an openwin include file,
X11/Xos.h.  It was changed by Sun's patch 108376-36.  If I edit
xlwmenu.c to use the older version of this file, the build succeeds
completely.  If I use the newer patched version, the build fails
100% of the time, independent of the compiler version (cc or gcc).

These details are specific to solaris 7; but the build fails in the
same way on solaris 8 and 9.  The patch numbers may be different.

I am not sure if its possible to workaround this in the ./configure
script.  I did not find any set of switches that would make it work.
Maybe it is purely a Sun/Openwin problem.
