Suddenly I need GMP and MPFR?

Thank you; I should've checked that first.
I'm not sure I understand how GCC uses these libraries. If I'm cross-
compiling for AVR, shouldn't the library be built on AVR? This
creates a new chicken-and-egg problem, doesn't it?
If I build GMP/MPFR for Mac OS X using Xcode (assuming it'll even
build; apparently there are issues with Apple's GCC), that will build
libraries that execute on OS X/i386. Is that the only capacity in
which GMP/MPFR are used by GCC? Or does it attempt to generate target
code that uses it?
