Similar problem on Solaris 8. There's no good way of replacing a 
configure based build by a fixed header file. It would be better to run 
pcre configure as part of the php configure. When building for Solaris 
8, I e.g. need to redefine several defines:

typeset file=ext/pcre/pcrelib/config.h
cp -p $file $file.saved
sed \
   -e 's/#define HAVE_READLINE_HISTORY_H 1/#define 
HAVE_READLINE_HISTORY_H 0/' \
   -e 's/#define HAVE_READLINE_READLINE_H 1/#define 
HAVE_READLINE_READLINE_H 0/' \
   -e 's/#define HAVE_STDINT_H 1/#define HAVE_STDINT_H 0/' \
   -e 's/#define HAVE_STRTOQ 1/#define HAVE_STRTOQ 0/' \
   $file.saved > $file
