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