CVS tags: HEAD
WARNS6 cleanup (1803 warnings).
ANSI function declarations.
Rename local variables that shadow globals.
Use string functions from libc instead of creating our own.
Remove void casts for unchecked function returns.
Spell parameter correctly.
Don't try to return a value from void functions.
Remove compat library requirement (gtty -> ioctl).
Add new function "dowarp" that calls warp() from play.c. (Taken from
Change chars that are used for numeric values to shorts so they can be
properly used as array indexes.

** C version by Eric P. Allman 5/76 (U.C. Berkeley) with help
** from Jeff Poskanzer and Pete Rubinstein.
** I also want to thank everyone here at Berkeley who
** where crazy enough to play the undebugged game. I want to
** particularly thank Nick Whyte, who made considerable
** suggestions regarding the content of the game. Why, I'll
** never forget the time he suggested the name for the
** "capture" command.
** Please send comments, questions, and suggestions about this
** game to:
** Eric P. Allman
** Project INGRES
** Electronics Research Laboratory
** Cory Hall
** University of California
** Berkeley, California 94720
** If you make ANY changes in the game, I sure would like to
** know about them. It is sort of an ongoing project for me,
** and I very much want to put in any bug fixes and improvements
** that you might come up with.
** FORTRASH version by Kay R. Fisher (DEC) "and countless others".
** That was adapted from the "original BASIC program" (ha!) by
** Mike Mayfield (Centerline Engineering).
** Additional inspiration taken from FORTRAN version by
** David Matuszek and Paul Reynolds which runs on the CDC
** 7600 at Lawrence Berkeley Lab, maintained there by
** Andy Davidson. This version is also available at LLL
** and at LMSC. In all fairness, this version was the
** major inspiration for this version of the game (trans-
** lation: I ripped off a whole lot of code).
** Minor other input from the "Battelle Version 7A" by Joe Miller
** (Graphics Systems Group, Battelle-Columbus Labs) and
** Ross Pavlac (Systems Programmer, Battelle Memorial
** Institute). That version was written in December '74
** and extensively modified June '75. It was adapted
** from the FTN version by Ron Williams of CDC Sunnyvale,
** which was adapted from the Basic version distributed
** by DEC. It also had "neat stuff swiped" from T. T.
** Terry and Jim Korp (University of Texas), Hicks (Penn
** U.), and Rick Maus (Georgia Tech). Unfortunately, it
** was not as readable as it could have been and so the
** translation effort was severely hampered. None the
** less, I got the idea of inhabited starsystems from this
** Permission is given for use, copying, and modification of
** all or part of this program and related documentation,
** provided that all reference to the authors are maintained.
** NOTES TO THE MAINTAINER:
** There is a compilation option xTRACE which must be set for any
** trace information to be generated. It is probably defined in
** the version that you get. It can be removed, however, if you
** have trouble finding room in core.
** Many things in trek are not as clear as they might be, but are
** done to reduce space. I compile with the -f and -O flags. I
** am constrained to running with non-separated I/D space, since
** we don't have doubleing point hardware here; even if we did, I
** would like trek to be available to the large number of people
** who either have an 11/40 or do not have FP hardware. I also
** found it desirable to make the code run reentrant, so this
** added even more space constraints.
** I use the portable C library to do my I/O. This is done be-
** cause I wanted the game easily transportable to other C
** implementations, and because I was too lazy to do the doubleing
** point input myself. Little did I know. The portable C library
** released by Bell Labs has more bugs than you would believe, so
** I ended up rewriting the whole blessed thing. Trek excercises
** many of the bugs in it, as well as bugs in some of the section
** III UNIX routines. We have fixed them here. One main problem
** was a bug in alloc() that caused it to always ask for a large
** hunk of memory, which worked fine unless you were almost out,
** which I inevitably was. If you want the code for all of this
** stuff, it is also available through me.
