The following fixincludes patch resolves the current ia64-*-linux-gnu
bootstrap failures caused by the recent constant expression changes.
This fix is similar to Andreas Schwab's recent patch to fix this
problem
directly in glibc's headers.

By also fixing this problem via fixincludes, we enable gcc to continue
to bootstrap on existing IA-64 Linux distributions. Tested on an SGI
altix running SGI ProPack 2.3, ia64-unknown-linux-gnu, with a complete
bootstrap, all default languages, and a "make check" in the fixinclude
directory. Without this patch, the bootstrap fails building libgcj.
Ok for mainline?
