[ANNOUNCEMENT] New: luajit-2.0.4-1

[Yaakov Selkowitz]

The following packages have been added to the Cygwin distribution:

* luajit-2.0.4-1
* luajit-devel-2.0.4-1

LuaJIT is a Just-In-Time Compiler (JIT) for the Lua programming
language. Lua is a powerful, dynamic and light-weight programming
language.  It may be embedded or used as a general-purpose, stand-alone
language.

Yaakov,

Thanks for this!  I can use your 64-bit patch to build luajittex on 
64-bit Cygwin.  Two questions:

1. Do you plan to send your patch upstream?  I had some correspondence 
with the author last year in which he said he would welcome a patch to 
make luajit build on 64-bit Cygwin.

2. Why did you use the -fexceptions flag in your build?  The build 
succeeds without that flag, and luajit still works AFAICT.  (But I don't 
really know how to test it.)

Unfortunately, upstreaming takes time (particularly when dealing with
the many misconceptions people have about Cygwin) so I've admittedly
been lax in that regard.

I'm just taking their word for it:

http://repo.or.cz/w/luajit-2.0.git/blob/8715ae6:/src/lj_err.c#l20

In particular, see line 50-55, although perhaps that only applies to
ELF?

I have to send the patch to upstream TeX Live anyway, so I could just 
copy the luajit author.

I'm not sure; I find that discussion ambiguous.  On the other hand, 
there's no mention of -fexceptions or -funwind-tables in the Makefiles, 
and src/Makefile explicitly says (line 150) that there's probably no 
need to change CFLAGS.

I did this, and he just applied the patch (with credit to you) as git 
commit 076d625.
