Sorry for taking so long.  I've browsed various mailing list archives
about the `G_INLINE_FUNC' problem (which is similar), but didn't find
any satisfactory explanation.  The workaround that's been applied boils
down to an `#ifdef __APPLE__' that avoids "extern inline" when on
Mac OS X.

The glib bug is http://bugzilla.gnome.org/show_bug.cgi?id=492152 .
The patch:
http://trac.macports.org/projects/macports/attachment/ticket/13006/glib2-inline.patch .

So, let's try to get a better understanding of what's going on...

Can you try the same, but compiling with "gcc -O2" this time?  This
should force function inlining.
