It appears that your <sys/mman.h> header file is defective in that it
doesn't work correctly in ANSI C mode.  I suggest you complain to your
vendor and see if they have a fix available.  In the meantime, you can
probably circumvent the problem by changing "MAP_FAILED" in the above
line to "(void *)MAP_FAILED".
