But it isn't working.

On your system, do you expect that given:

struct
{
  int foo
} bar;

bar baz[] =
{
  0,
  5
}

bar blinth[] =
{
  0,
  6
}

bar *toot[] =
{
  baz,
  blinth
}

that toot is {0,5,0,6} ?

Doesn't seem to happen on Windows (even if everything's in one file.)

on windows, you get something like
{-2512342,993424123,-235235235 ... etc...

Is this really valid C?

Here's something from the manual page for ld:
       -warn-common
              Warn  when a common symbol is combined with another
              common symbol or with a  symbol  definition.   Unix
              linkers  allow  this  somewhat sloppy practice, but
              linkers on some other  operating  systems  do  not.
              This  option  allows you to find potential problems
              from combining global symbols.

I think Windows is one of those "other operating systems".  Is the description
above what you're trying to do with GB_CLASSES[]?
