Are you sure that think this is correct ? Afaict things should work,

Jon, any ideas why xserver disables -fvisibility=hidden ? Should we
remove that line or there's something subtle that requires the
behaviour ? For example: relying on symbols that are not marked as
exported or alike.
From past (ancient) experiences and reading the wiki correctly,
combining -fivisiblity=hidden + dllimport/dllexport should work fine ?
As far as I recall, the issue was simply that if you use
-fvisibility=hidden for a PE/COFF target, gcc will warn 'visibility
attribute not supported in this configuration; ignored' on every single
symbol declaration with default visibility, which is really annoying...
