--disable-visibility made it work. Thanks!

The version of gcc is 3.4.0. It seems to me like the compiler supports
the feature just fine (which the configure script detects correctly).
But that the linker (gld 2.15) doesn't. Perhaps it is as easy as
upgrading binutils (I will try that later). At least we can rule out
that any part of glib (including the configure script) is to blame,
right?
