Patch to fix the problem with the conflicting types.

compiling qt-4.6.0 with webkit on Solaris 10 with Studio 12, I see the following error:

"css/CSSComputedStyleDeclaration.cpp", line 570: Error: Ambiguous "?:"expression, second operand of type "int" and third operand of type
"WTF::PassRefPtr<WebCore::CSSPrimitiveValue>" can be converted to one another.
"css/CSSComputedStyleDeclaration.cpp", line 571: Error: Ambiguous "?:"expression, second operand of type "int" and third operand of type
"WTF::PassRefPtr<WebCore::CSSPrimitiveValue>" can be converted to one another.

I've submitted a patch which has passed compilation.

Someone who actually knows something about the application might
be better to check the very small patch I submitted.  I'm just
trying to get QT compiled.  I don't know when I'll have the port
complete.

Updated version of the patch to more correctly represent a "0" (as previously used in the conditional) to a type acceptable by the SS12 compiler

This is an updated patch that fixes a webkit component to compile on Solaris 10 with the SunStudio12 compiler.

Simply, a 0 (int) causes a problem for strongly typed SunStudio 12 C++ and this patch uses a more normalized form of an "empty" pointer so that the compilation will continue.

I'm sorry to sound like a broken record, but please do follow <http://webkit.org/coding/contributing.html> to contribute code. In particular, the patch lacks a ChangeLog, and doesn't have r? bit set for review.

Without a ChangeLog, the patch cannot be landed, and without being marked for review, it isn't visible in review queue.

Proposed patch which compiles correctly in qt-4.7.1 with webkit enabled on Solaris 10 with SS12 C++ compiler

This fix is against webkit head, but works for the webkit distributed with qt-4.7.1.  This fix is similar to the one in https://bugs.webkit.org/attachment.cgi?bugid=56198 which passed muster.
