Yes!  I've been toying with the idea of doing something similar myself,
specifically, making it compile with the gcc warning options I gave
before, possibly weakened if experience proves it necessary.  (For
example, it may demand major work to make it clean wrt -Wcast-qual
-Wwrite-strings...proper const-poisoning is _not_ trivial.  Even a few
of my own programs have resorted to a "deconst" trick, which strips the
const qualifier from a pointer in a way that doesn't trip -Wcast-qual.
Part of the problem, of course, is ANSI C's weird notion of pointer
compatability, which makes some pointer combinations clash when they
needn't...like casting "char **" to "const char **".)
