Subject: Attempting to fix import/export linkage on Windows.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=d263334030cee35a84248867a7facf51a3f1abe4;p=simgear.git

Attempting to fix import/export linkage on Windows.

Hopefully this tells the Expat headers not to do any clever
declspec(import) or export stuff, which we don't want since we only
use the symbols within SimGearCore, and don't export them.
