I knew that the zero-size arrays were GCC-specific, but I thought that
they were part of the C99 standard.  Of course, I can't find the web
site where I read that now, so maybe it was just my fevered imaginings.

I had hoped to avoid yet another layer of pointer referencing, but it
looks like the language is going to force me into it.  <sigh>  If some-
one there knows a way to accomplish this with portable C, please speak
up.  (At least this will get rid of the horrible "array of chars" syntax
required to initialize a zero-length array in GCC.)

Separating the string data from their indices will allow them to be
declared as const, so that should get them into the ".rodata" section of
the resulting assembly; the Adobe Glyph List vector is already there.
Is this what you mean by "read only memory"?

If the string data does not have the indices mixed in with it, I will
probably just build the initial glyph list at run time which will avoid
having it in two places, so all of the static data should be in

Let me know if this approach will work for you.
