What about testing for MAP_FAILED?

From the man page out here:

RETURN VALUES
     Upon successful completion, mmap() returns a pointer to the mapped
     region.  Otherwise, a value of MAP_FAILED is returned and errno is set to
     indicate the error.

(Yes I know that MAP_FAILED is defined to ((void *)-1) out here, but on
systems where it returns 0, MMAP_FAILED might be defined to zero, no?...)
