I did find these:
(cygwin-1.5.21-1)
cygwin-1.5.21-1/newlib/libc/sys/linux/include/complex.h
(gcc-g++-3.4.4-2)
usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/backward/complex.h
usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/complex

Now that I noticed the third one, the second one makes sense; it is 
probably a wrapper complaining that you should '#include <complex>'. 
However those are C++ headers, not C headers.

The first one does have "newlib" in the path, for whatever that's worth.
