Description:
------------
While compiling under OS X, the compiler warns us about a probably unwanted type conversion:

php-7.0.0RC1/ext/date/php_date.c:2196:6: warning: absolute value function 'abs' given an argument of type
      'long long' but has parameter of type 'int' which may cause truncation of value [-Wabsolute-value]
                                        abs(utc_offset / 60),
                                        ^
php-7.0.0RC1/ext/date/php_date.c:2196:6: note: use function 'llabs' instead
                                        abs(utc_offset / 60),
                                        ^~~
                                        llabs


given input is long long, we probably want output to be long long too or we might have a year 2038 problem (https://en.wikipedia.org/wiki/Year_2038_problem)


Test script:
---------------
./configure

Yeah, that was seen actually in the build logs all the time. But not critical IMHO in first place as the TZ offset can't grow that much. Still the warning should be probably fixed.

Thanks.

This has been fixed in the meantime.
