Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting

Backed out "fix for PR 7575". It was bogus.

/usr/src/usr.bin/lex/Makefile puts FlexLexer.h into /usr/include/g++,
but flex still generates "#include <FlexLexer.h". As a result,
C++ sources flex generates failed to be compiled.

Add ``%{'' and ``%}'' to one of the examples so that you can actually
