We never got this to work I think, and it would hardly have a cc1plus
binary.

cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC 
but not for C++ [enabled by default]
address@hidden:/usr/local/tmp/lilypond$ g++ --version

Looks like we should get rid of that warning option.  It's not
apparently in our codebase, so it is likely introduced by autoconf.
Actually, I can't even find it in a work tree of mine when using plain
grep, so either Mike has a different autoconf, or it is implicitly
included for some reason by his g++.  At least on my version of g++, I
have not been able to trigger it by using -Wall.
