signbit macro uses __signbitf function although not compiled in?
|Reported by:||andreasf||Owned by:||axeld|
The public header
posix/math.h defines a
signbit macro to call functions
__signbitf et al. However these cannot be resolved at runtime.
The implementation for this function seems to be in
libroot/posix/glibc/arch/generic/s_signbitf.c but that directory does not seem to be compiled in - there's no
../Jamfile only includes the specific architecture.
Mono's configure for instance detects
signbit but later fails to link. (It can work without, but gets confused by the current situation.)
