[PHP-DEV] Warning in Windows build (related to safe_emalloc)

[Zeev Suraski]

C:\Projects\php5\Zend\zend_alloc.c(231) : warning C4018: '<' : 
signed/unsigned mismatch

It appears that VC doesn't like the comparison:
lval < LONG_MAX - offset
because offset is unsigned, it turns LONG_MAX-offset to unsigned as well, 
and ends up comparing an signed with unsigned.  Maybe we should explicitly 
cast LONG_MAX-offset to long?
