I admit to giving GCC the benefit of the doubt. I may be naïve that way,
trusting the tools to do what seems like the obviously right thing to
do.

If GCC lets us down, we could try something like the yesno version in
drivers/net/ethernet/chelsio/cxgb4/cxgb4_debugfs.c. GCC not doing the
right thing with that would be violating the standard.
