Summary:                    configure does not find floor, pow, rint, sqrt in
tgmath.h
Description: 
configure is not finding floor, pow, rint, or sqrt.

checking for floor... no
checking for pow... no
checking for rint... no
checking for sqrt... no

But they're there:

$ egrep -w "#define (floor|pow|rint|sqrt)" /usr/include/*.h
/usr/include/tgmath.h:#define pow(Val1, Val2) __TGMATH_BINARY_REAL_IMAG
(Val1, Val2, pow, cpow)
/usr/include/tgmath.h:#define sqrt(Val) __TGMATH_UNARY_REAL_IMAG (Val,
sqrt, csqrt)
/usr/include/tgmath.h:#define floor(Val) __TGMATH_UNARY_REAL_ONLY (Val,
floor)
/usr/include/tgmath.h:#define rint(Val) __TGMATH_UNARY_REAL_ONLY (Val,
rint)

The check has nothing to do with whether it can be found in a header file,
but rather whether the function actually exists in a library file.  If it's
not finding it in the libm.so library, then your installation is out of
spec with the Linux standard.  Complain to your OS vendor that they screwed
the pooch.

See 'man pow' for details.
