Description:
------------
ezmlm_hash() returns different values depend on OS (32bit vs. 64bit)

The problem is with types used in the algorithm. 
Easy fix that works for unix and linux is to change 
unsigned long h = 5381L;
to
unsigned int h = 5381;

because int is always 4byte type on linux and unix.






Reproduce code:
---------------
run ezmlm_hash() on linux 32bit and 64bit and compare results

Expected result:
----------------
the same results

Actual result:
--------------
different results
