Rule of thumb - if they are both in the same BLFS book, you can follwo
the book's instructions, usually they just install side by side because
they are different packages

1.2 gives /usr/lib/libg{d,t}k-1.2 and 2.6.7 gave
/usr/lib/libg{d,t}k-x11-2* for the main libraries. Imlib-1 is pretty
obsolete and only used occasionally (I'm an icewm user, even that can be
told to do without imlib).

Yes, but again libxml is pretty obsolete - gnome1 might use it, but I
think the only current gnome-1 application is gnucash.

I'll pass on that one.

Not exactly. The glib-1/gtk-1/gdk-pixbuf and glib-2/atk/pango/gtk-2
combinations are very different. I have a couple of things using gtk-1
(e.g. xmms).
For gcc, things get even murkier. gcc-3.4.3 is sufficiently stable and
common now, that most people won't need an older version. However, the
libstdc++ side of it has changed across the versions - some stuff,
particularly binaries, needs the old libstdc++ from 3.3 and BLFS tells
you how to run with both. Some people will want to see how gcc-4
handles their favourite packages - as long as you don't try to put
multiple versions of gcc in the same directory, you should be fine (e.g.
normal version in /usr and other version in /usr/local or /opt or
/home/me then set PATH according to which one you want to use).

Pass. In general, BLFS sometimes provides alternatives and you get to
pick the one you prefer.
