There is a similar problem in Mandriva:
http://qa.mandriva.com/show_bug.cgi?id=18984

Welvaart has found 3 solutions:
a) build that setupgeneral.o without -fvisibility-inlines-hidden
b) explicitly set the visibility of the method to "default" in qdir.h
(using Q_EXPORT)
c) gcc patch to give an explicit class visibility declaration higher
precedence than a global (commandline) -fvisibility-inlines-hidden
option: http://qa.mandriva.com/attachment.cgi?id=3772

What do the you think? Where is the bug, in gcc?
