I think you do have to compile. ED, the files that you provided me when I
was having trouble with this were some type of binary files. For instance,
what is available from the PROJ4 site are the text based datum shift files:

ALASKA
CONUS
...etc.

After compilation, there will be binary files of the same name, with the LLA
extension:

ALASKA.LLA
CONUS.LLA
...etc.

I think what I found was that simply having the text files in there was not
enough... you had to have the LLAs (which you can only get by compiling).

FWIW, these files have to be in two places if you're using BOTH cgi and
php-mapscript. CGI looks for them in C:\proj\nad, and PHP-MapScript looks
for them in c:\proj. I'm sure you could re-configure this at compile time,
but, I typically use the pre-compiled binaries.

Kieran, if you want, I can zip up my PROJ directory and e-mail it to you. In
my opinion, we should put up a compiled version of the PROJ directory on the
web site for windows users.
