Would that combination suppress warnings about unused variables, as well
as unused parameters?

"-Wsign-compare" would turn on the signed-comparison warnings, although,
unfortunately, there don't appear to be options to turn on the other
warnings that require "-W" in 2.95[.x], such as the warning if "A
nonvolatile automatic variable might be changed by a call to longjmp"
(which I think older compilers warn about with just "-Wall"), or the
warning if "A function can return either with or without a value", etc..

(Sigh.  *WHY* did the GCC people bundle a large collection of warnings
under "-W", with no way of selectively turning them on or off?)
