Description:
------------
PHP 5.5 builds are broken with GCC 3.4.6 due to the inline assembler
changes in zend_operators.h (in aa12cdc361)

Since the old assembler code path works for GCC 3, I suggest we simply
retain it with appropriate #ifdef's.  This may make someone's life
easier, e.g. during platform migration. 

Note RHEL 4.9 with GCC 3.4.6 was released 2 years ago. GCC 3.4.6
itself was released 6 years ago.

Currently compiling PHP 5.5 with GCC 3.4.6 fails with:

The patch is attached.  It was tested with GCC 3.4.6 and 4.1.2 on 32
and 64 bit Oracle Linux.

This seems to be related to GCC 3 not having support for __builtin_offsetof().

Let's fix it like this instead (see patch). Could you please try it?
 [2013-05-07 18:10 UTC] sixd@php.net 
Doh! I'd initially patched it that way but hadn't included stddef.h correctly.
Your patch works.  Since you have Zend karma, can you apply it?

I've confirmed that Ard's patch also fixes cygwin, which is still on 3.4.4. Thanks!
