* many files: made some functions static; removed "extern int errno;". * frozenmain.c: fixed bugs introduced on 24 June... * flmodule.c: remove 1.5 bw compat hacks, add new functions in 2.2a (and some old functions that were omitted). * timemodule.c: added MSDOS floatsleep version . * pgenmain.c: changed exit() to goaway() and added defn of goaway(). * intrcheck.c: add hack (to UNIX only) so interrupting 3 times will exit from a hanging program. The second interrupt prints a message explaining this to the user.
