I have just installed cygwin on this system.
When I try to compile a small program, I get this error:

/usr/lib/gcc/i686-pc-cygwin/4.5.3/cc1.exe: error while loading shared
libraries: cygmpfr-4.dll: cannot open shared object file: No such file
or directory

ldd agrees:

        cygmpfr-4.dll => not found
        cygz.dll => /usr/bin/cygz.dll (?)

Where would I find this library? (source not much help w/out working
compiler :-/

Cheers ... Duncan.
