>From Phil's regression hunter: Search converges between 2002-04-21-trunk (#74) and 2002-04-
28-trunk (#75).
It is caused by this patch:
        * c-common.c (shorten_compare): Simplfy conditions leading to
        the generation of a warning.
But again it is not really a regression since the code did not warn about the code when it was not 
in dead code, sorry.
And also it is warning about the dead code before GCC figures that it is dead code.
