[Bug bootstrap/17281] New: gcc 3.4.2-20040829, build failure, osf 5.1b, floatformat.c

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

Dunno if alphaev68-dec-osf5.1b is a critical platform for this release.  If it
is, this is a release-stopper.

I'm using make 3.79.1, the vendor-supplied assembler and linker, and the
vendor-supplied compiler.  Scripts and logs attached.

gcc 3.3.4 works in this configuration.  I haven't tried gcc 3.4.1 with the
vendor assembler and linker.  gcc 3.4.1 does build if I bootstrap it with gcc
3.3.4 and gnu binutils 2.15.
