I always remove -lm from every link line.  IIRC, all which is included
in libm.a is also in libcygwin.a?  E.g. take this:

$ nm /usr/lib/libm.a | grep _log1pf
00000000 I __imp__log1pf
00000000 T _log1pf

$ nm /usr/lib/libcygwin.a | grep _log1pf
00000000 I __imp___log1pf
00000000 T __log1pf
00000000 I __imp__log1pf
00000000 T _log1pf

So why should I include libm?
