hehe.
didn't anyone tell you that you have to allocate memory before you can
gets into it?
char *arg[4];

gets(arg[1]);
man gets:
gets() reads a line from stdin into the buffer pointed to

by s until either a terminating newline or EOF, which it
replaces with '\0'. No check for buffer overrun is per-
formed (see BUGS below).
My guess is it's purely coincidental that your code worked on DOS.
