Looking at the file, I'm guessing that you're on i386. It looks like
that particular header uses anonymous unions on i386 (only) for some
reason, and in hg, I've added the -pedantic-errors CFLAG. Usually the
system headers are better at dealing with such things. For that matter,
I'd expect gcc to ignore the setting in system headers anyway.

At any rate, can you try changing -pedantic-errors to -pedantic in
mk/gcc.mk?

It's actually had two heads for ages, but one of them wasn't
intentional. As for named branches, I'm generally not a fan. They're a
relatively new feature, so they don't really seem like the ‘hg way’ to
me. At any rate, I don't intend much maintenance in that branch in the
future. The only reason it's there is because there were build problems
with the release.
