I attempted to build newlib-autotools-branch at home, and the build
failed in the same way as I've been seeing at work. My system at work
and my system at home both run Debian Sarge. If *no one* else is
seeing this bug, I must assume it's somehow Debian related. Although,
I'd be quite mystified as to the mechanism. There's a number of Fedora
boxes at work as well. Come Monday, I'll give the build a shot on
Fedora.

Enjoy your weekend. Cheers,
Shaun
