Thanks. I still need approval for the doc and build parts, as well as
the Darwin and DJGPP changes. For the latter two, I've included the
patch in a x86_64-apple-darwin11.4.2 build, verifying that -gz is
rejected as expected (no idea if the are any working gas and gold ports
that would support the option). For DJGPP, I've tried a
i386-pc-solaris2.11 x i586-pc-msdosdjgpp cross. While the specs
additions look correct, trying to compile even the most trivial program
