From:             php at hottub dot ca
Operating system: AIX 5.1 ML4
PHP version:      4.3.3RC4
PHP Bug Type:     Compile Failure
Bug description:  'with-zlib' or 'with-bz2' causes 'redeclaration' of 
php_image_type_to_mime_type

Description:
------------
Trying to compile 4.3.3RC4 on AIX 5.1 ML4 using IBM 
Visual Age C version 6.0 (cc).

PHP compiles properly with other options without issue, 
but when issuing configure with the --with-zlib and --
with-bz2 options, compilation fails.  Here is the 
command being executed:

cc  -Iext/standard/ -I/build/php-4.3.3RC4/ext/standard/ 
-DPHP_ATOM_INC -I/build/php-4.3.3RC4/include -I/build/
php-4.3.3RC4/main -I/build/php-4.3.3RC4 -I/build/php-
4.3.3RC4/Zend -I/usr/local/include -I/build/php-
4.3.3RC4/ext/xml/expat  -I/build/php-4.3.3RC4/TSRM  -g  
-c /build/php-4.3.3RC4/ext/standard/image.c -o ext/
standard/image.o  && echo > ext/standard/image.lo

And the error output:

"/build/php-4.3.3RC4/ext/standard/image.c", line 
1029.21: 1506-343 (S) Redeclaration of 
php_image_type_to_mime_type differs from previous 
declaration on line 60 of "/build/php-4.3.3RC4/ext/
standard/php_image.h".
"/build/php-4.3.3RC4/ext/standard/image.c", line 
1029.21: 1506-050 (I) Return type "unsigned char*" in 
redeclaration is not compatible with the previous 
return type "const unsigned char*".
make: *** [ext/standard/image.lo] Error 1

The system does not have mysql installed (IBM's DB2 is 
installed, but not enabled as a configuration option).  
There are also a number of warnings during compilation 
that all relate to mysql.h:

"/build/php-4.3.3RC4/ext/mysql/libmysql/mysql.h", line 
181.14: 1506-731 (W) The '_Export' keyword is not 
supported on the target platform.  The keyword is 
ignored.

This is the output from configure when the options are 
enabled:

00Configuring extensions00
checking for ZLIB support... yes
checking if the location of ZLIB install directory is 
defined... no
checking for gzgets in -lz... yes
checking whether to enable bc style precision math 
functions... no
checking for BZip2 support... yes
checking for BZip2 in default path... found in /usr
checking for BZ2_bzerror in -lbz2... yes

I can make a shell account available for the assignee 
to test themselves.
