Changes between beta-test release of Feb. '88 and initial release:
- many files renamed to remove "flex" prefix
- input() routine added to compressed and fast skeletons
- unput() routine added to compressed skeleton
- -d, -ce support for fast scanners
- symbol table extended to avoid ugly casts of ints <-> char *'s;
this may relieve MS-DOS woes
- actions are now separated with YY_BREAK instead of simple "break"'s
- fixed bug causing core-dumps if skeleton file could not be opened
- fixed bugs in logic deciding which options cannot be intermixed
- initial start condition can now be referred to as <INITIAL>
- fixed bug which would incorrectly computer trailing context
count for a pattern like "(foo){3}"; now this is considered
"variable length", even though it isn't.
- block comments allowed between rules
- misc. typos corrected
