Description:
------------
PHP 5.2.13 doesn't compile with Sun Studio compiler on Solaris 10 Sparc. Configure works fine (as in 5.2.12), Make fails on ext/date/php_date.c file with:

A diff between 5.2.12 and 5.2.13 shows the culprit (php_date_llabs vs. llabs and/or ifndef HAVE_LLABS, because of bug 50266 and bug 50930)

Jose Marcio, thanks for the patch. Compiles and works fine now!

This also affects Solaris 10 x86 with Sun Studio compiler.

I submited this patch as it's simple and will work for every combination of OS and compiler.

But the result is that php_date_llabs function isn't defined as inline. This may be an important performance issue only if this function is called very very frequently (I don't know if this hypothesis is true and I don't believe).

The correct solution could be to redefine this with some other checks in order to use the correct inline declaration syntax. Another solution, as this is a really simple function is to declare it as a macro. Something of the kind :

#define php_date_llabs(i)  ((long long) ((i) >= 0 ? (i) : -(i))

with sun studio 12 update, __inline is now recognized as synonymous for inline. this patch makes this code compilable on all platforms

(C99 standard does support inline keyword)

I can commit this bug, if no one has any objections to it.
