Description:
------------
# ./configure ... --enable-zip ...

# make

/data/prj/php-5.2.14/ext/zip/lib/zip_name_locate.c: In function `_zip_name_locate':
/data/prj/php-5.2.14/ext/zip/lib/zip_name_locate.c:67: error: `strcasecmp' undeclared (first use in this function)
/data/prj/php-5.2.14/ext/zip/lib/zip_name_locate.c:67: error: (Each undeclared identifier is reported only once
/data/prj/php-5.2.14/ext/zip/lib/zip_name_locate.c:67: error: for each function it appears in.)
make: *** [ext/zip/lib/zip_name_locate.lo] Error 1

Test script:
---------------
PATCH? or TEST?
This is only with AIX433. AIX 5.1 and beyond has strcasecmp defined in <string.h>. I do not know if ./configure would add an AIX433 somewhere to make it automatic to add strings.h.

I am able to fix it with:
File: ext/zip/lib/zip_name_locate.c
   +34  ^L
   +35
   +36  #include <string.h>
   +37  #ifdef _AIX
   +38  /* for AIX433 actually! */
   +39  #include <strings.h>
   +40  #endif
   +41 
   +42  #include "zipint.h"
   +43 
   +44  ^L

Expected result:
----------------
successful build.

Actual result:
--------------
/data/prj/php-5.2.14/ext/zip/lib/zip_name_locate.c: In function `_zip_name_locate':
/data/prj/php-5.2.14/ext/zip/lib/zip_name_locate.c:67: error: `strcasecmp' undeclared (first use in this function)

Sorry, dont know how to make a patch - keeps saying it is text/lisp or v.v.

My suggestion:
in file add ext/zip/lib/zip_name_locate.c near line 34

^L

#include <string.h>
#ifdef AIX433
#include <strings.h>
#endif

and add -DAIX433 to CFLAGS before starting ./configure (if it is not done automaically already)

the fix sounds wrong if earlier version of AIX has it in string.h, as it always includes strings.h.

I would suggest to add a test for this function in configure.ac (as we can use it everywhere in PHP). Adding the necessary iteration for AIX (using string.h and then strings.h on failure.
