Description:
------------
Trying to compile PHP 5.3.2 on HP-UX 11i (B11.11) for command-line usage with : 

./configure --prefix=$HOME/bin/php-5.3.2 -with-zlib=$HOME/bin/zlib-1.2.3 --enable-zip --with-pcre-regex --enable-exif  --with-gd --enable-mbstring --with-readline=$HOME/bin/readline-6.1 --with-snmp --enable-soap --with-pear --with-zend-vm --enable-zend-multibyte --with-libxml-dir=$HOME/bin/libxml2-2.7.6 --with-png-dir=$HOME/bin/libpng-1.4.1

I get : 
checking for readline in -lreadline... yes
checking for rl_pending_input in -lreadline... no
configure: error: invalid readline installation detected. Try --with-libedit instead.

Looking at config.log, configure script is trying to compile this against libreadline : 

#line 78181 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char rl_pending_input();

int main() {
rl_pending_input()
; return 0; }

I checked in readline.c from versions 6.1 and 5.1, l_pending_input is declared as an int, not as a function.

Can you show the compiler error from the config test? What compiler are you using?
