The Tk toolkit shell, Wish, seems to work better and pass more of
the tests if compiled without optimization.
People who are having weird problems with other packages may want
to compile without "-O".
Or get a new version of gcc.
If you use gcc with no optimisation, that is what it means. There
will be no register variables except for ones declared explicitly
register. No intermediate values will be kept in registers. In other
words, it gets "a bit" inefficient. Much better to just update your
compiler...
