Auto is an artifact of the past.  Back then we were hoping to support
more than one GC engine.  Auto means `Use any GC if found, do not use it
if not found' as opposed to `definitely use Boehm or definitely do not
use anything'.

You have to manually specify none there:

	configure --with-gc=none

If you do that from the Mono build directory, `mono' and `oldmono' are
wrappers generated by libtool.  The real binaries typically live under

So you can do:

	gdb --args .libs/mono helloworld.exe

Or just do a make install and use as you normally would.
