mman.h and mman.c are from mman-win32 project (https://github.com/witwall/mman-win32).
It is a light implementation of the mmap functions for MinGW.
PageSize and NumberOfProcessors are obtained through GetSystemInfo function
It is the substitution for sysconf(_SC_PAGESIZE) and sysconf(_SC_NPROCESSORS_ONLN) for MinGW.
