do you happen to build gcc on Tru64 UNIX V5.0A with the bundled Compaq cc
as the bootstrap compiler?  If so, this compiler most likely miscompiles
gcc.  You should try to bootstrap with the latest version of Compaq C from

	http://h30097.www3.hp.com/dtk/compaqc_ov.html

Please note that you will need the OSF-DEV pak to be able to use that
compiler.  Another common problem seems to be lack of swap space: you may
need up to 700 MB to successfully bootstrap gcc.

Hope this helps.
