they are: - changed the makefile - prototyped functions - eliminated pathnames.h since all it does is #include <paths.h> - used gettytab.h for various function declarations - verified stack usage at 712 bytes - eliminated dummy gethostname() function. Instead, get it from libc. This exposes a problem with gethostname. See PR#59 for details. - eliminated a dependancy on strftime for the moment by calling ctime() instead. - Added GNO-formatted versions of the man pages.
