installation bug in egcs-19990927 on Alpha EV6

["David B. Serafini" <dbs at nersc dot gov>]

This bug happens on Compaq DS20 and Compaq XP1000 systems; both use
the Alpha 21264/EV6 CPU.

This bug happens on both RedHat v6 and SuSE v6.1 versions of Linux.

It happens with both gcc-2.95.1 release and egsc-19990927 snapshot.

The bug happens during installation.  The only non-default option is
the `--prefix=' option given to configure.

The commands given were:
 gunzip -c egcs-19990927.tar.gz | tar xf -
 cd /tmp/egcs927
 <egcs-dist-dir>/egcs-19990927/configure
--prefix=/usr/local/pkg/egcs-19990927
 make

The relevant part of the output, including the error message, is:
