According to Bruno Haible on 4/7/2007 4:23 AM:
> $ ./show-portability copysignf
> libc macosx-10.3
> libcygwin cygwin
> libm cygwin
The show-portability script output is a bit confusing for cygwin. Yes,
the fuction copysignf is provided by linking with cygwin1.dll. But on the
link line, there is no -lcygwin, just -lc; and -lm is an empty library
since everything on cygwin belongs to -lc.
