i was working on getting gd 2.0.7 and php 4.2.3 to compile, undefined functions error, had to modify about 4 lines, 3 in php's source, ext/gd/gd.c and ext/gd/gd_ctx.c find anyline in those two files that matches



io_ctx->free



and make it



io_ctx->gd_free



and it should compile.

I had to made some modification to enable and compile gd2.0.1 with php4.2.3 here it is:

get and untar gd2.0.1 beta

if your server as mine doesn't have any X support or you don't want it, open Makefile to disable xpm support, find "gdxpm.o"  in lines and delete it (because even if you don't ask for it in libs cmd it will compile in and you'll get an error when loading requesting libXpm)

remove any libgd1.so.xx 

"make install"

in php goto ext/gd dir

modify gd.c and add "#define HAVE_LIBGD20 1" at the beginning

compile (don't forget giving the --with-jpeg-dir and png too), install and it should works
