Yeah, but that new format was just begging for a NAK. No one wants a new
format layout. They want C code. But unfortunately, when we use enums
for flags and such, the macros have no idea how to handle it. I may try
to work out a way to let those same macros be able to export the value
with the enum name.

I'll try to figure out something.
