Yeah, but that does move the problem to the other side doesn't it? So
if you (as a pure test of course) were to remove the variable
completely from the included header and just declare it manually with
PGDLLSPEC in your file, it should work?
Ugly as it is, I wonder if there's a chance we could just process all
the headers at install times and inject the PGDLLIMPORT. We know which
symvols it is on account of what we're getting in the DEF file.
Not saying that's not a very ugly solution, but it might work?
