I recently noticed if you want to compile PHP using the suncc compiler,
there are no useful default flags set by configure. Therefore if there
are no objections I want to commit the following patch that introduces
usefull cflags (actually those used by php distributed by sun) for the
suncc compiler if the user didn't provide his own cflags. In addition it
makes sure that --enable-debug works for suncc. I tested the patch with
sunstudio 11 and sunstudio 12 c compilers. The patch is for 5.3 so I
won't commit this to 5.2.
