Log Message:
-----------
so CHECK_PROTOTYPE_EXISTS() is woefully busted in numerous ways. assumes c++,
has a bad symbol test, results in unused var warnings, and doesn't work with
preprocessor-wrapped symbols coming from system headers. former versions of
CHECK_SYMBOL_EXISTS() almost did exactly what we need (a simple (void)symbol;
test just like AC_CHECK_DECL) but was bastardized in recent versions so it now
spews an error too (it's busted and has been reported).
