That sounds entirely reasonable.

Actually, the only true problem here is that the obvious way of
answering this question---adding to the language-specific union a new
entry containing an obstack* / char* union plus a flag---increases the
size of a symbol (logically it doesn't have to, but C layout and
alignment rules apparently add some padding). To avoid increasing its
size, there is the aesthetically distateful option of adding a flag
byte AFTER the language-specific field; or perhaps we could call it
a union tag. Harumph.

You don't? Good grief, man, what has happened to your sense of
adventure, your thirst for danger?
