Bug#212912: gcc-3.3: [alpha] Linux linker/loader does not support -mieee-conformant
[CCing to debian-alpha]
As Chris (currently listed as package maintainer for gcc alpha) seems
to be away, I'll ask on debian-alpha (Falk?), if this patch should be
included. In that case the documentation should be changed to
explicitely mention Debian instead of Linux.
