In fact the fix I suggested was the origin of the failure to compile php_apache.c and should be disregarded.

So I manage to compile everything on regular version 4.3.0 but with the following fix:

diff ext/standard/php_image.h.orig ext/standard/php_image.h 
48c48
<   IMAGE_FILETYPE_IFF,
---
>   IMAGE_FILETYPE_IFF

diff ext/standard/dl.c.orig ext/standard/dl.c              
139c139
<       handle = DL_LOAD(libpath);
---
>       handle = (void *)DL_LOAD(libpath); /* FTU */

but maybe it will be even better to declare handle as DL_HANDLE and to cast:
handle = (DL_HANDLE)DL_LOAD(path);
like for zend_extensions.c

diff Zend/zend_extensions.c.orig Zend/zend_extensions.c
33c33
<       handle = DL_LOAD(path);
---
>       handle = (DL_HANDLE)DL_LOAD(path);      /* FTU */



diff ext/standard/file.c.orig ext/standard/file.c
29a30
> #include "dlfcn.h"            /* FTU */
105a107,108
> #undef XtOffsetOf       /* FTU */
> #undef closesocket    /* FTU */

diff sapi/apache/php_apache_http.h.orig  sapi/apache/php_apache_http.h
11a12
> #include "dlfcn.h"              /* FTU */

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

And please provide any patches in 'diff -u' format..

The compilation still fails (using xlc).

I suggest the following fix for php_image.h because xlc is very picky about comma left at the end of a structure:

diff  php-4.3.0-latest/ext/standard/php_image.h php-4.3.0-latest/ext/standard/php_image.h.org
20c20
< /* $Id: php_image.h,v 1.19 2002/06/24 19:36:26 helly Exp $ */
---
> /* $Id: php_image.h,v 1.19.4.1 2002/12/31 16:35:33 sebastian Exp $ */
48c48
<   IMAGE_FILETYPE_IFF
---
>   IMAGE_FILETYPE_IFF,

Sorry I don't have diff -u. Which option is the best ?

$ diff -u php-4.3.0-latest/ext/standard/php_image.h php-4.3.0-latest/ext/standard/php_image.h.org

Please get new snapshot, I fixed that php_image.h issue
already, the revision in php_image.h should be 1.19.4.2

The other error has to be investigated..

Good, :-), php_image.h works fine on my platform.

Next problem I encounter is dl.c and zend_extensions.c
I suggest the following syntax fixes:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
diff dl.c dl.c.orig
141c141
<        handle = (void *)DL_LOAD(libpath); /* FTU */
---
>       handle = DL_LOAD(libpath);

with dl.c is
/* $Id: dl.c,v 1.79.2.3 2003/01/29 15:40:24 edink Exp $ */
