gcc compiling needs some defines (-DAUX_SOURCE) and maybe a call to
setcompat() in the init phase of the program. This is handled automagically
by cc

Did you have a getty on one of the serial ports ? I always have,
so I can fire up a comm program on my girlfriends SE and kill -9
the mac when it hangs.

You can also try command-control-I (for interrupt) or command-control-E
(for exit) if you have MacsBug 6.2.anything installed. That ususally
gets you out of the mac environment. (You might have to type
^Jscreenrestore^Jstty sane^J by hand afterwards, though)

You could also use THINK C under A/UX 24bit mode, but you can't use the
built-in "Run" command, you have to build an application to test it.

Now, if Symantec hears this:

I WANT A A/UX-COMPATIBLE THINK C, THANK YOU ! (After all, I bought the
darned thing to get support...) Oh, well, I know how it is with users
shouting and management setting other priorities. C++ would be nice,
as would ANSI C, and extensible editor, (and/or better support for
external editors... like keyboard shortcuts in all dialogs !)

That's it.
