I can leave the default netbsd. However, I am sure mono will never run
properly on NetBSD 1.6 because of the lack of native threads support. I'll
make the changes anyway.

Indeed, these redefinitions are odd, but the register indices are not in the
same orders under NetBSD, hence the shuffle. I'll check if this is still
necessary, since it is a port from an 1.1.4 patch. About the FreeBSD
changes, I'll check against the SVN although the 1.1.7 is not really that
old.


The changes to mini-x86.c in particular seemed unnecessary, since
pthread_attr_init() is now called by default.  SA_STACK->SA_ONSTACK is also
already defined for netbsd in  mini-x86.h when MONO_ARCH_USE_SIGACTION is
defined, so no need to redefine it in mini.c.  As for the register indices,
that would require the changes, of course.
 

Ok, I did not dig that deep when I ported the patch. There were many changes
between 1.1.4 and 1.1.7 :) Agreed for pthread_attr_init and SA_ONSTACK.
 
I also noted that redefining register indices is not needed if
HAVE_WORKING_SIGALTSTACK is defined. But since it can be disabled using
--with-sigaltstack=no, it would break the compatibility with NetBSD's
sigcontext. I think its best to leave it there.

 
Impressive hacks in libgc, too.  You jumped right out of my sandbox with
that stuff.  :)
 

Thanks, glad to hear that ;)
 
I joined with this message the updated patch to include your suggestions.
