(that was silly) + * 3.04.96 Per repeated request of a single person: autoskip defaults to off. + * 15.05.96 -v added. They want to know the version. + * -a fixed, to show last line inf file ends in all zeros. + * -u added: Print upper case hex-letters, as preferred by unix bc. + * -h added to usage message. Usage message extended. + * Now using outfile if specified even in normal mode, aehem. + * No longer mixing of ints and longs. May help doze people. + * Added binify ioctl for same reason. (Enough Doze stress for 1996!) + * 16.05.96 -p improved, removed occasional superfluous linefeed. + * 20.05.96 -l 0 fixed. tried to read anyway. + * 21.05.96 -i fixed. now honours -u, and prepends __ to numeric filenames. + * compile -DWIN32 for NT or W95. George V. Reilly, * -v improved :-) + * support --gnuish-longhorn-options + * 25.05.96 MAC support added: CodeWarrior already uses ``outline'' in Types.h + * which is included by MacHeaders (Axel Kielhorn). Renamed to + * xxdline(). + * 7.06.96 -i printed 'int' instead of 'char'. *blush* + * added Bram's OS2 ifdefs... + * 18.07.96 gcc -Wall @ SunOS4 is now slient. + * Added osver for MSDOS/DJGPP/WIN32. + * 29.08.96 Added size_t to strncmp() for Amiga. + * 24.03.97 Windows NT support (Phil Hanna).
