I don't know, but it sounds like you did.

Unlikely, because you would have gotten an import error (along with a
winerror of 126):

    $ fgrep 126L /usr/include/w32api/winerror.h | head -1
    #define ERROR_MOD_NOT_FOUND 126L

The above is most likely the problem.  You cannot use two C runtimes in
the same program.  You will have to either use all Win32 or all Cygwin
components.  A mixture of the two is a recipe for disaster...
