e95aed631d (main): Use return to exit, undoing yesterday's change. 
The last OS that we could find where this wouldn't work is
SunOS 3.5, and that's too old to worry about now.

ffa4c58acb (struct yyltype): Define members even when not 
doing locations.  This is more consistent with yacc.c, and it
works around the following bug reports:

c827f760f6 Minor spelling and typographical fixes. Use @acronym consistently. 
Standardize on "Yacc" instead of "YACC", "Algol" instead of "ALGOL".
Give a bit more history about BNF.

6db10d14be Be consistent about 'bool'. 
* src/complain.c (warning_issued): Renamed from warn_message_count; now bool.
(complaint_issued): Renamed from complain_message_count; likewise.

* src/main.c (main): Use exit to exit with failure.

* src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
rather than 1 and 0.
* src/main.c (main): Likewise.
* src/getargs.c (getargs): Likewise.
* src/reader.c (reader): Likewise.

* src/getarg.c (getargs): Remove duplicate code for
"Try `bison --help'".

* src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
What was that "2" for?

* src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
* src/getargs.c (usage): Likewise.

* src/getargs.c (getargs): When there are too few operands, report
the last one.  When there are too many, report the first extra
one.  This is how diffutils does it.

95f2c9fe7d Do not create a temporary file, as that involves security and 
cleanup headaches.  Instead, use a pair of pipes.
Derived from a suggestion by Florian Krohm.

Also, some other minor changes to avoid GCC warnings.
