GD configuration problem

I'm having trouble getting PHP to admit that the GD package exists. Or
several other packages that I would expect to see.

Some months ago I wrote a PHP script that does some simple processing on
images. GD had the functionsI needed, so I used it. I got it working and
used it a few times.

Then I wanted to add some more functionality which was available in the
ImageMagick package. So I rewrote it  (saving the original) using 
ImageMagick.

But my PHP turned out not to support ImageMagick. So I downloaded a 
newer PHP,
and turned on ImageMagick in the config file.

But it didn't work -- my PHP didn't include ImageMagick. After a few 
frustrating
tries to get ImageMagick working, I went back to the old version of the 
script.

But now the GD version doesn't work (error messages below).

I now have three different PHPs on my computer:
* The one that was included with my Cygwin installation
* The one that was included in my XAMPP distribution
* One that I downloaded directly from the PHP site.

I get the same errors on all 3.

Okay, that's the lead-in. Here are the error messages:
