After applying these two patches, it built fine.
 [2005-03-04 16:42 UTC] sniper@php.net 
Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

..and if (when) it fails, provide the patche(s) against to these source (CVS HEAD branch) and put them online somewhere where we can download them. The patches get messed up in this bug system..
 [2005-03-05 06:54 UTC] amd at store20 dot com 
Used yesterday's CVS snapshot. One problem still existed (xmlrpc).
my_free is just a ugly wrapper to free.

http://amd.store20.com/files/2005-Q1/php5_xmlrpc_gcc4_compile_fix_bug_32150.patch
 [2005-04-23 01:37 UTC] jorton@php.net 
This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

Oh, missed this one.  The my_free() problem was fixed this morning, using exactly the fix you proposed!
