But again, even if sqrtl is not part of the library, this is not a GCC issue.
We provide builtins for faster usage and not to get around libc not including
the function.

Anybody have enough __asm__ foo to write a inline assembly macro taking a long
double operand and returning one, which I can use to call fsqrt directly in
inline assembly? I'm scoping the docs, but have never found i

It may be C99, but since it doesn't work on 90% of the machines in the world,
it is a bit of a stretch to call it portable. My point is no standard mandates
you round down a long double (where you don't round down a

sqrtl is C99 so it is portable, just not to cygwin. That is not our fault that
cygwin does not provide a C99 math library.

Turns out the proposed solution of using sqrtl is not portable. In particular,
all code using it fails to link on Windows using cygwin. Any idea how to make
this work portably? I still don't understand why it is OK

Use sqrtl then if you don't want the rounding.
