# Compared to other libraries, compiling this one is a mess.  The
# reason is that we have several source files that have two different
# sets of behaviour, depending on whether they're intended to be part
# of the viewer or the map server.
#
# Unfortunately, the affected code is a rat's nest of #ifdefs, so it's
# easier to play compilation tricks than to actually fix the problem.
