	FYI, the original YACC was severely broken with respect to alias
analysis -- not bison, not byacc, but the original YACC.  I don't know how
common that version is anymore or that programming style.  That is one
program I know of that will be affected by enabling strict aliasing with
normal optimizations in EGCS, if it matters.
