Haven't had time/motivation to build B2 in months.

Last few times, I used autoconf/make. There were source code changes
that required -D changes in the project files, and I got tired of
chasing them up.

The versions I built/run/shipped had no signal handler,
or always set it to be disabled. Slightly speeding up
the screen refresh wasn't an issue when most (game) users
complained that BasiliskII was too fast :-)

Hi Mike,

I've committed the first two patches you sent. Sorry it took so long,
but I've been really busy lately.

I know it's not related to your code, but looking at the code brought
up some serious concerns.

Particularly struct sigsegv_info_t that's re-declared would be
incomplete if HAVE_MACH_EXCEPTIONS is on.

I've added a big FIXME there, and haven't had the time to investigate
further - but if Screen_fault_handler ends up accessing the extra
fields in that struct - it will be a serious bug (accessing memory
past the end of that structure). This really needs to be fixed (again
it's not your changes, but still..)

Re: [B2-devel] Fixes for BasiliskII and SheepShaver for Mac OS X 10.4 and 10.5 ppc and intel

[Alexei S. <ale...@gm...>]

I've just fixed the issue I described by moving sigsegv_info_t struct
declaration to the sigserv.h

I'd appreciate if someone could verify that this doesn't break the
build for their favorite platforms.

Hi Alexei,

Don't worry about being busy. Thanks for accepting the patch.

I have checked-out of cvs and built and run like so with no problems:

ppc32 10.5.6:

B2 --disable-standalone-gui --enable-vosf --enable-sdl-video 
--enable-sdl-audio --enable-addressing=real --without-esd --without-gtk 
--without-mon --without-x

SS --disable-standalone-gui --enable-vosf -enable-sdl-video 
--disable-sdl-audio --enable-addressing=real --without-esd --without-gtk 
--without-mon --without-x

ia32 10.5.6:

B2 ./configure --disable-standalone-gui --enable-vosf --enable-sdl-video 
--enable-sdl-audio --enable-addressing=real --without-esd --without-gtk 
--without-mon --without-x --enable-jit-compiler

SS --disable-standalone-gui --enable-vosf -enable-sdl-video 
--disable-sdl-audio --enable-addressing=real --without-esd --without-gtk 
--without-mon --without-x --enable-jit
