crosstool-ng/patches/gcc/4.1.1/100-uclibc-conf.patch
Yann E. MORIN" 1906cf93f8 Add the full crosstool-NG sources to the new repository of its own. 
You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(
