The attach change fixes PR middle-end/68743 on hppa*-*-hpux*. In compiling
c99_functions.c in libgfortran, floor ((double)x) was transformed to floorf(x)
but
floorf is not available on hppa*-*-hpux*. The change simply adds a
libc_has_function
check to prevent the transformation.
Tested on hppa2.0w-hp-hpux11.11 and hppa64-hp-hpux11.11.
Okay for trunk?
