glibc 2.21 - Master is frozen solid at -26 degC.

[Carlos O'Donell]

It's -26 degC in Deep River Ontario and the Ottawa river
is frozen solid ... and so is master.

Please TO: me on all patches and I'll ACK them throughout
the day EST time.

Manual fixes, obvious comment cleanups, and build fixes
within machine-specific files are OK.

Thank you to everyone who has already posted test results
for your machine. Please keep testing.

If you need help, please ask for it.

Cheers,
Carlos.
