#It appears the guilty optimization is "-frename-registers", leaving that one 
#out allows the build to proceed normally.  -fexpensive-optimizations may be OK,
#it was removed while debugging an issue that ultimately turned out to be due

#Note that this testing was done without the gcc-pr32889.patch.
