// In various files of the Goddard subsystem, there are miscellaneous
// unused rodata strings. These are likely byproducts of a printf macro
// that was stubbed out as "#define printf", letting printf calls expand
// to no-op comma expressions. (IDO doesn't support variadic macros, so
// "#define printf(...) /* nothing */" wasn't an option.)
// This macro is separate from the gd_printf function; one probably
// forwarded to the other, but it is hard to tell in which direction.
