Easy way out: add the -mno-cygwin parameter to CFLAGS.  That means "use mingw
headers and libraries" to produce a windows only executable (no cygwin dll
dependencies); this will work if the package you are compiling doesn't depend on
libraries not supplied by mingw.

I'm not sure about the standard, but complex is defined in libstdc++ wich is c++
not c, and I don't have it in gcc 3.4.4 only on 4.0.2 (not distributed with
Cygwin yet).
