RE: [Tinycc-devel] longjmp not working on 64bit

[Christian Jullien]

Hello Grischka,

I've just tested my OpenLisp www.eligis.com with mob and, except for 2 or 3
details I'm catching and I will try to fix, port on Windows x64 is almost
complete now (even with my huge non regression tests suite).

Thanks for your very good job and support.

Christian

See http://repo.or.cz/w/tinycc.git/commitdiff/ad351b20

It doesn't support new x64 windows unwinding though, so better not
use it to jump across window procedures, threads and some such.
