at least, f2c works very good together with djgpp, so You should
consider a change ... ;-)

These files are "shell archives" : bourne shell scripts which "unbundle"
when interpreted by "sh" - I have some doubts whether You'll get happy 
with them. 
Perhaps You should get "ordinary" zip-files ?

s.a.

Yup
