README for ptc as enhanced by Tor Lillqvist.

$Log:	README,v $
Revision 1.10  90/03/28  00:51:09  tml (Tor Lillqvist)
Fixed outputting 'char' as the C type for Pascal 'Char'.  This
is wrong because Pascal Chars are of an unsigned nature while
C chars usually are signed.

Revision 1.9  90/03/27  02:19:18  tml (Tor Lillqvist)
Removed void casts from ptc.h.  The Ultrix 3.1 compiler didn't
like them.
Use unsigned chars.  That was what we had supposedly used all the
time, but we had n fact used normal (signed on most systems) chars.
(In the ptc-generated C code, that is.)  This caused a problem
when using char variables as array indices, for instance, as
ptc believed the char to have a value range of 0..255 when in 
fact the signed char had the range -128..127.

Revision 1.8  90/03/25  09:31:05  tml (Tor Lillqvist)
Fixed Fopen.
Don't put the original ptc.p in the tar archive, put a backwards
diff from the current instead.

Revision 1.7  90/03/25  08:58:59  tml (Tor Lillqvist)
Fix in ptc.h: added missing __LINE__ arguments to Fopen.

Revision 1.6  90/03/23  16:24:51  tml (Tor Lillqvist)
In ptc.h: set eoln flag at eof.  Use putc, not fputc.

Revision 1.5  90/03/17  17:32:02  tml (Tor Lillqvist)
Fixed Seek in ptc.h (parens were wrong).

Revision 1.4  90/03/13  19:57:16  tml (Tor Lillqvist)
Fixes to ptc.[ph].  Even better laziness.

Revision 1.3  90/03/13  08:23:28  tml (Tor Lillqvist)
Include all RCS logs in the tar file, not only the one for ptc.p.

Revision 1.2  90/03/13  08:13:34  tml (Tor Lillqvist)
By mistake I used fgetc in ptc.h.  getc is better of course (faster).

Revision 1.1  90/03/13  08:10:49  tml (Tor Lillqvist)
Initial revision


I have made some relatively minor enhancements to the ptc Pascal-to-C
translator.  The RCS logs are included the file RLOGS.  A translated
version of ptc.p for bootstrapping is included in the tar archive.
The original version of ptc.p can be generated by applying the
ptc.p.backdiff diff.
