Also note that %D in "printf" and "scanf" will also confuse SCCS.  Furthermore,
it will greatly upset the System III/System V version of "printf", which
says "%X" means "hex with capital A-F" and *only* allows the "l" prefix to
indicate a long argument.

Moral: Don't use %D or %F.  %ld and %lf will do just as well, and won't
break SCCS or fail on USDL systems.
