I was unable to build a working extension with the provided files, I 
have rebuilt the config.m4 file to be compliant and now a working 
module can be built and I've verified working properly on the following 

FreeBSD 5.2
Mac OSX 10.2.x
Mac OSX 10.3.x

(actually I can only test the rd_graph function because I don't have 
any PHP scripts that perform any other function calls.)

I wanted to embed the extension into PHP and as the documentation 
explained, I moved the config.m4, rrdtool.c and php_rrdtool.h to 
php-4.3.10/ext/rrdtool, did the buildconf --force, configured PHP with 
'--with-rrdtool' and it embedded the functions in PHP as expected 
however, trying to use the embedded rrd_graph function always results 
in a 'invalid rpn expression' yet if I build PHP with 
'--with-rrdtool=shared'. it makes a shared extension and it works 

Making the functions embedded is mainly a Mac OSX preference and I have 
been extremely successful doing this with other extensions.

I've made changes to the source files using the zlib extension 
(ext/zlib) and the xdebug extension as examples/footprints and while it 
did make the compiled code smaller, it did not make the embedded 
rrd_graph function work properly.

I can provide root access to the server in question by ssh or through 
tightVNC (for Windows) or you can download the *nix source and build 
your own *nix cleint or you can use your own VNC client if you have 
another preference.
