Thanks for the bug report. It would be helpful if you can send the
output of the configure script. It looks like it detects mmap() etc.,
but not the sys/mman.h header file.

On a regular Unix system, these are defined in the <sys/mman.h>
header. Do you happen to know if MinGW has that header file or the
equivalent?
