Old Status: Feedback
Status: Open
Old Bug Type: Sockets related
Bug Type: Compile Failure
Operating System: AIX 4.3.3 with C compiler 3.x
PHP Version: 4.0.6
New Comment:

Using my configure line reported earlier, PHP 4.1.0RC3 compiles without the reported bug.

(I'd like to see the #ifndef-#define-#endif construct nevertheless, it's the art of
defensive programming :-) .)

But compilations succeeds only if you set

  CC='cc -ma' ; export CC

prior to running configure; otherwise make fails in the linkage step because alloca() is available
only as a builtin function, not as a library function, on the given system/compiler environment.
Perhaps it is possible to check the need for the -ma option during configuration?
(The only purpose of -ma on the given system ist to activate the builtin alloca().)

Can you try if this still happens with latest RC

http://www.php.net/~zeev/php-4.1.0RC3.tar.gz

If so, can you try replacing the line 

#define _XOPEN_SOURCE_EXTENDED

with

#ifndef _XOPEN_SOURCE_EXTENDED
#define _XOPEN_SOURCE_EXTENDED
#endif

and see if it works?

Feedback.

configure --enable-discard-path --enable-force-cgi-redirect --enable-memory-limit --enable-dbase
--enable-ftp --enable-calendar --enable-wddx --enable-socket ; make

ext/sockets/sockets.c line 38 causes the system-defined
_XOPEN_SOURCE_EXTENDED to be redefined from a numeric value to an empty value. This later breaks
compilation because the numeric value will be used in another system header file containing a
statement

#if _XOPEN_SOURCE_EXTENDED==1
