And speaking of casts and C/C++...suppose you have package "foo" and you
want to build "foo" with CC=g++ -- that ought to be legal, right?
<pathto>/foo-src/configure --prefix=... CC=g++
But that means on cygwin/mingw, if foo uses libtool then the cwrapper
will be built using ${CC} -- that is, g++. Bang; you're dead -- because
the cast is required with C++, isn't it? (IIRC it's not just a warning,
it's an error, if the cast is missing).
