I don't have ready access to a UW2 system, but 2.95.2 worked for me
on UW7 which I believe to be equivalent in all pertinent ways.
[ pause ] 
I just kicked off a your configure line below on UW7.1.0 with GNU make
and SCO /bin/cc and was unable to duplicate it.  (full three-stage in 17
minutes.   Nice.)

The alloca thing is often caused by mixing and matching compilers; if
you configured with GCC but built with /bin/cc, you'll get behaviour
like this.  Is it possible that you've crossed the streams at some
point?  Did you have CC in your environment during the configure?

Did you do a 'make bootstrap' or a 'make'?

Was this during the build of stage1 or during the build with stage1/?
(Please include more context in your report.)

No.

Ick.  You have no right to complain if a 'make install' nukes your
system files...

None of SCO's makes are up to the "source in one place, object in
another" that works so well with the GNU projects.  I highly recommend
using GNU make.  It's available on www.sco.com/skunkware if you don't
want to build it.
