glibc-no-long-double-math.patch
I agree that even for __NO_LONG_DOUBLE_MATH we should provide *l prototypes
(certainly for __USE_ISOC99, not sure about __USE_MISC alone), just redirecting
to the non-l functions, though tgmath.h nor signbit/finite/... macros which
just use sizeof obviously can stay as is.
This patch is totally untested...
