This stuff is all fixed in the bundled version of GD in PHP 4.3. Use
--with-gd without any path when you build 4.3.

I would also like to say that we found another way to bypass this
issue.
The color space problem comes up when we superimpose (imagecopy)
different images together dynamically - we are adding button images to
a 8-bit background image.
We are able to avoid this issue by limiting the color table size for
each image involved. This solution should work for most cases.
Still, problems would arise if:
1) we need to combine multiple images with non-overlapping, large color
tables
2) the quality of the base image requires the full 256 colors to look
decent

OK, we downloaded and compiled the snapshot as recommended..
Then we made this test script and called it like this:
http://<SERVER>/php/testTrueColorImg.php?asd=test.png
so that I.E would see the .png at the end of the URL (seems to help it
understand that this is a png better sometimes)
-------
<?php
// create the image
$image = ImageCreateTrueColor(200,200);
$bg = ImageColorAllocate($image,0,0,0);
$tx = ImageColorAllocate($image,255,128,128);
$white = ImageColorAllocate ($image, 255, 255, 255);
ImageFilledRectangle($image,0,0,200,200,$bg);
//ImageString($image,3,70,90,"it works !",$tx);
ImageTTFText ($image, 20, 0, 10, 20,$white,
"/homespace/geneport4/fonts/Arial.ttf","Testing...");
// send the image
header("content-type: image/png");
ImagePNG($image);
?>
-------
It seemed to help the text look a little better, but not as good as it
does with an 8-bit image.
Another note, the image appears to look better in IE 5.5 than it does
in I.E. 6.0.sp1 but this may just be related to that fact that we
tested this on different computers/monitors.

Please try using this CVS snapshot:
http://snaps.php.net/php4-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php4-win32-latest.zip
Use your original configure line, but don't pass '--with-gd' any path.
(This will make it use the bundled GD library)
If this fails too, please provide a short example script
which can be used to reproduce this.

Because of color-space issues that came up with using the simple 8-bit
imageCreate() method, I have moved to using the imageCreateTrueColor()
function.
If I create and image using imageCreateTrueColor, and then try to write
text onto it using ImageTTFText, the text will not be anti-aliased. I
have negated the color index being passed into ImageTTFText as an
attempt to fix the issue, but there was no change.
Configure line
----------------
./configure --prefix=/homespace/geneport4/system/core/php --enable-wddx
-enable-sigchild --enable-trans-sid
--enable-inline-optimization
--with-apxs=/homespace/geneport4/system/core/apache/bin/apxs
--without-mysql --with-oci8
--enable-track-vars --enable-gd-native-ttf
--with-gd=/homespace/geneport4/system/core
--with-freetype-dir=/homespace/geneport4/system/core
--with-png-dir=/homespace/geneport4/system/core
--with-zlib=/homespace/geneport4/system/core
