The general consensus seems to be that I should show as much info as  
is reasonably possible. For this, extensions need to be able to  
register the summary information they can provide. I've come up with  
a couple of different ideas for the syntax on this:

1) Add a new parameter to PHP_NEW_EXTENSION(), i.e.:

     PHP_NEW_EXTENSION(standard, array.c base64.c basic_functions.c  
browscap.c crc32.c # \ etc,
                        ,,,, \
                        [Standard functions

Regex type:--with-regex=${REGEX_TYPE}])

2) AC_DEFUN() a new macro, i.e.:

     PHP_SUMMARY_INFO([Standard functions], [Extension: Enabled
Regex type: --with-regex=${REGEX_TYPE}])

These are just random examples based on the standard extension,  
obviously. Anyone like either of these or have a better idea?
