Thanks.  A C-only bootstrap (alpha-dec-osf5.1b and alpha-dec-osf4.0f)
completes with this patch, but if I build with all languages, cc1 segfaults
in malloc building the stage 2 libdecnumber:

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I cannot get a proper stack trace, though.  The file compiles at -O.
