Since it is in cross-tools, some added configure options need to be  
added. I was successfully using graphite optimizations after gcc-final  
in cross-tools.

--disable-isl-version-check --with-isl=/cross-tools --with-cloog=/ 
cross-tools

Graphite has been around for a while, since before gcc 4.5. I'm not  
sure where most of any problems would stem, other than from improper  
versions. Version matching seems to be a key, as well.

As I've said before in the past, I used graphite with gcc 4.7.3  
without issues, but with 4.8.1 I would have quite a few segmentation  
faults, even early in the build with ncurses and readline, and if  
those were built with graphite options, it would cause any app linking  
against those to segfault.

I'm doing more tests with gcc 4.8.1.

Thanks for your input, Martin.

Sincerely,

William Harrington
