I've just seen recent binutils ditatrabe about how we have copies of
math libraries floating between glibc, gcc and the kernel.

What do we gain from putting it in gcc?
	- ?

What do we gain from putting it libc?
	- More frequent package updates?
	- IMO easier to debug?

Why are there math functions in libgcc in the first place?
Historical reasons?

Okay.
