modified the lock file directory to the correct position for NeXT

A big effort was done to make everything compile under -Wall.
tipx does compile already, but tiprz/sz still needs more work.

made PULSE dial the default in hayes.c

Tested the z-modem receive. It now works under NS3.2 (did not before, gave Floating point exception error).

I have included fat binaries for i386 and m68k.
