Description:
------------
Received this compile warming while compilling:
(...)/php_date.c: In function 'date_format':
(...)/php_date.c:1040: warning: incompatible implicit declaration of built-in function 'llabs'

So did a grep -R llabs ./ and get:
./win32/php_stdint.h:static __inline int64_t llabs( int64_t i ) { return i >= 0? i: -i; }
./ext/date/php_date.c:			case 'Y': length = slprintf(buffer, 32, "%s%04ld", t->y < 0 ? "-" : "", llabs((timelib_sll) t->y)); break;
./ext/fileinfo/tests/magic:# from Ruda Moura <ruda@helllabs.org>

it seems llabs its only available for windows, is this right ??

Can I filter all warmings, I spotted this one because I canceled compilation right in begining and seen that, but in midle of all those lines can't spot nothing more.. 


Regards



Reproduce code:
---------------
grep -R llabs ./ in php package source.
