The copy used for testing is:

Configured with: /vol/gnu/src/gcc/gcc-3.0-branch-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --enable-shared --disable-nls --enable-libgcj alpha-dec-osf5.1

Sure: the patch went in on 2001-07-19 (i.e. before the 3.0.1 release), the
prerelease above is two months newer, i.e. well into the 3.0.2 phase.

It certainly passed make check since at that time I was working to get a
patch in to enable libgcj support on Tru64 UNIX.

but this doesn't give too much information.  I've checked /usr/.smdb./*.inv
and found that /usr/ccs/lib/cmplrs/cc/as[01] (the assembler passes invoked
by as -oldas) are from the vanilla OSFCMPLRS510 subset, whereas
/usr/ccs/lib/cmplrs/cc/ld (i.e. ld) is from OSFPAT00035800510 (i.e. Patch
358.00)

As I said, make and make check both passed with the above snapshot.  I can
try a fresh bootstrap from current 3.0 branch sources, just to make sure,
but this may take some time.

Certainly: if we find out that e.g. a specific ld patch is required, this
should clearly be documented in the installation notes.
