I'm not sure if this new naming is avoidable in the long run, but
I'd much rather use attributes instead of __imp__*. Two points:
1. __imp__ is deprecated. It should really be _imp__ if anything.
2. why not use the following instead of using __imp__:
extern int foobar __attribute__((dllimport));
At some point, we'll need to recompile everything to change the
references of dllimported vars appropriately. Might as well start
now. IMO, that's what development snapshots are for, but I do
understand the problem it causes.
