History
Joseph Myers 81dca813cc Use copysign functions not __copysign functions in glibc libm. 
Continuing the move to use, within libm, public names for libm
functions that can be inlined as built-in functions on many
architectures, this patch moves calls to __copysign functions to call
the corresponding copysign names instead, with asm redirection to
__copysign when the calls are not inlined (all cases are inlined
except for IBM long double for powerpc soft-float / e500v1).  This
eliminates the need for an inline function defining __copysign in
terms of __builtin_copysign.

Tested for x86_64, and with build-many-glibcs.py.
