that would be ok I guess, though I would prefer not to change the
behaviour magically like that (another variable when debugging people's
problem reports)

ok, I think (C) wins then :-)

|It will be happy if we can use functions in font.c, won't it?

yes, but we can't

The problem is that the sawfish.ui code doesn't know the pango font type
is supported by sawfish, not what the user's preference is. If it
decides to use pango fonts, when they're not supported, things will
work very badly!

I've just changed things so that sawfish.gtk.widgets.font is generated
by configure from a font.jl.in file, it has a variable substituted into
it that lets it know when pango is available.

Please update from cvs and let me know if it still works for you,
