May be it is possible to avoid adding new entries. I looked a
little... Two kinds of statements can be exported:
procedures/functions and (on some platforms) variables.

tvarsym contains a field varoptions that is a set of tvaroption.
Tvaroption already has vo_is_exported as a possible value.

tprocsym has a field is_global : boolean (unfortunately, only under
{$ifdef GDB}). This field could be easily changed to byte with 3
possible values: 0 - local, 1 - global, 2 - global and exported. That
could cause no changes in binary PPU structure and no changes in other
parts of compiler where this field is already used (only a typecast byte to
boolean is needed). Am I right?
