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)

gcc -lm seems to find libm:

$ cat m.c
#include <stdio.h>
#include <math.h>
int main(char** argv) {
  double off_the_floor = 4.5;
  printf("floor(%lf)=%lf.\n", off_the_floor, floor(off_the_floor));
  return 0;
}

$ gcc -lm m.c
$ ./a.out
floor(4.500000)=4.000000.

(Without the -lm, gcc says "undefined reference to `floor'", as expected.)
