That's libz.  The old Makefiles had a line about whether you wanted to 
include libz or not.  If you did, then gzipped files would be 
uncompressed on read automatically.  If you didn't, you were responsible 
for ungzipping the MPS files.

That could be a feature test in configure--if you have libz, use it; if 
not, either gunzip the MPS files or do nothing.  Offer --no-libz option to 
override if you have it but don't want to use it.
