You don't have to be subscribed to report a bug there.  I'm forwarding
your report:

Thanks for the report.  Which compiler did you use?  Asking because the
current code has something like

#ifdef _MSC_VER
# define _CRT_SECURE_NO_DEPRECATE 1
#endif
#include <stdio.h>
#include <stdlib.h>
#ifdef _MSC_VER
# include <direct.h>
# include <process.h>
# include <io.h>
#else
# include <unistd.h>
# include <stdint.h>
# ifdef __CYGWIN__
#  include <io.h>
# endif
#endif

which would include process.h but only for MSVC.

My MinGW cross compilation environment includes process.h from unistd.h,
but I'm not sure that we can expect that (the cwrapper doesn't use
_P_WAIT on cygwin).

Thanks,
Ralf
