Various vendors extended PCX in several incompatible ways before it faded
into obscurity in the early 90's.  That's not a variation of PCX that we've
seen before, so that's not supported.   We support "DEG" there.

It's not obvious to me how N381448.476 would be DMS anyway.14 minutes and
48.476 seconds?   That's pretty fictional precision.

It would be relatively easy to add support to pcx.c for this format.  If you
do so, please contribute the patch back to benefit the next person that
finds his data locked in this format.
