	ACK, thanks!  Somehow, I fail to find any mention of this
	“setting” on http://ipxe.org/.  (I've tried registering and
	logging in, but it hasn't allowed me to create the corresponding
	page myself, either.)

	… Or, one can use ${errno:int32} and get somewhat simpler labels
	(:memtest_1, :memtest_2; hopefully there're no implications for
	errno's greater or equal to 0x80000000.)

	Now, with all these features in place, aren't we headed towards
	designing one more fully-featured programming language?  And if
	there's some chance that we are, wouldn't it be possible to stop
	and implement some language already in existence instead?  (Or
	are we doomed to repeat the history?)

	ACK, thanks.  (Just like in C.)

	ACK.  (Indeed, I've carried all my experiments with it so far
	using a PXE version I've built.  It's at [1], if anyone's
	interested.  Check also [2] for why I've put it there.)
