Normand,

I think there's quite some confusion about how mapserv actually does
the lookup of the epsg file for getting the project parameters.
Therefore it's worth considering to embed the proj parameters in the
mapfiles whenever it's possible so as to minimize the external
dependencies of the tests.

In this particular case I did some investigation and found that
embedding that projection in c.\proj\nad\epsg could solve the issue on
the windows builders.

Perhaps we could alter the compare algorithm of the images using a per
pixel method with a proper tolerance considering the difference
between the rounding rules.
