[Bug ada/13750] New: Ada bootstrap failure on Tru64 UNIX: b_gnat[1b].o comparison failure

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Current mainline fails to bootstrap on Tru64 UNIX (both V4.0F and V5.1B),
using GNAT 3.3.2 as a bootstrap compiler:

Bootstrap comparison failure!
ada/b_gnat1.o differs
ada/b_gnatb.o differs
make[1]: *** [gnucompare] Error 1

This worked at least until 20040114.

The difference is already in the underlying generated .c files:
