Tru64 UNIX bootstrap failure in libjava

[Rainer Orth]

I've just tried to bootstrap current mainline on alpha-dec-osf4.0f/osf5.1,
and even after fixing the warning-as-error in cp/decl.c, bootstrap fails in
libjava:

cc1plus: out of memory allocating 21504080 bytes after a total of 124589216 bytes

Increasing the data size limit from the default of 128 MB to unlimited
(i.e. 1 GB) allows the compilation to succeed, but this was unnecessary
during the last bootstrap one week ago.

I'll have to investigate which patch caused that regression.
