[Groff] [OT] Patches for AT&T DWB and Heirloom troff |

Hello,
for those who are interested in other *roff distributions also I have patches
for two of them: AT&T DWB from 1993 and Gunnars Heirloom troff.
AT&T DWB:
I don't know if it's well-known but the source of AT&T DWB from 1993 is
available on http://www2.research.att.com/sw/download under EPL license. I
made some minimal changes to make it compile on OpenBSD, NetBSD and Linux.
There are still the usual warnings regarding sprintf and strcpy which I didn't
care about in the first step. Also there are a lot of shift/reduce and
reduce/reduce warnings from yacc which I will look into next time, but a parser
is generated and works for first tests. Also there are some hacks to set an
initial state for AT&T lex which I disabled, I will have to look into it also.
All book documents I had created in the past are generated with identical
appearance like from Heirloom or Plan9 troff. (There are few small differences
to groff--at the moment I don't know which tool has the bug ;)
Of course this version may not have support for UTF-8 or identifiers longer
than 2 characters (etc.).
If one is interessted I can send this patch.
Heirloom troff:
The Sourceforge version compiles on usual UNIX systems (but also with lots of
shift/reduce errors) and also works as expected--except on OpenBSD. There the
binary crashes with 90% probability. Posts can be found about this issue but
no solution for it. I have created a simple patch with which it works fine on
OpenBSD too. The issue is not OS dependend so it may cause functional problems
on other systems too.
