Sven,

I found the problem!  It is that you can't use the comma delimited format
for the projection string when using towgs84 since there is no way to
know that all the towgs84 arements are part of the same argument.

I changed it to this and it worked:

$projInObj = ms_newProjectionObj( "+proj=tmerc ".
   "+lat_0=49 ".
   "+lon_0=-2 ".
   "+k=0.999601 ".
   "+x_0=400000 ".
   "+y_0=-100000 ".
   "+ellps=airy ".
   "+towgs84=375,-111,431,0,0,0,0");

I would like to strongly encourage folks to use the "+" format for all
MapServer purposes!

Best regards,
