Last change on this file since fd5c672 was 44426cf, checked in by Joe Ciccone <jciccone@…>, 17 years ago
Updated to Glibc 2.6. This includes adding a sed to Coreutils and Gzip to rename their internal implementations of futimens which are incompatible with the implementation provided by Glibc. Added a target tripplet based optimization to glibc on x86 and 32bit build on x86_64 so that glibc will build properly now that i386 is no longer supported. Also added a note to the build variables page the i386-pc-linux-gnu is not supported by glibc.
