I think most apps that used to use libmp have transitioned to
libgmp, so I don't have much of an opinion on this change...

However, if the compiler as a builtin for the math.h-style pow()
function, and the builtin causes it to choke even when math.h
isn't #included, that's a bug in the compiler. The people who are
proposing that we make the base system LLVM-compatible should be
more forceful in insisting that LLVM be fixed. ;-) What do the LLVM
folks propose to do about all the (perfectly legal) programs out
there that have a variable called 'exp'?
