	# savvy about gdb's workings and the meaning of the "{}"
	# construct.  So the details maybe could be tweaked.  But the
	# basic purpose should be maintained, which is (a) users should be
	# able to interact with these variables with some care (they have
	# to know how to interpret them according to their real type,
	# since gdb doesn't know the type), but (b) users should be able
	# to detect that gdb does not know the type, rather than just
	# being told they are ints or functions returning int like old
	# versions of gdb used to do.

	# On alpha (and other ecoff systems) the native compilers put
	# out debugging info for non-aggregate return values of functions
	# even without -g, which should be accepted.
	# Irix5, even though it is ELF, counts as "ecoff" because it
	# encapsulates ecoff debugging info in a .mdebug section.
