You should be able to substitute gzopen() gzread() gzseek() 
gztell() appropriately for fopen() fread() etc.. in mapshape.c 
then you could keep the files in compressed form.

This is less of a performance hit then often thought
and in fact 'can' be faster if the data file is being read 
from a slow device. i.e. < CD , networked drive etc >
