State-Changed-Why:
    Can you report this to the cygwin developers at:
    http://www.cygwin.com/lists.html
    
    The standard C math libraries are not packaged with the
    FSF version of gcc, so this is a Cygwin packaging
    issue.

>Description:
long double math functions such as sinl() apparently missing from libraries built for GCC-3.0/Cygwin.
>How-To-Repeat:
Compile and link the following:

---------
#include <cmath>

int main()
{
    return std::sin((long double)(3.14));
}
----------

mark.cpp: In function `int main()':
mark.cpp:5: warning: return to `int' from `long double'
mark.cpp:5: warning: argument to `int' from `long double'
/cygdrive/c/DOCUME~1/abrahams/LOCALS~1/Temp/ccG6WrbC.o(.text$_ZSt3sine+0x13):mark.cpp: undefined reference to `sinl'
