libsane should be automatically detected (sane-config --libs).

-lsocket/-lsyslog should work with the same "fix" as in sane-backends.
This should also fix the #HAVE_VSYSLOG problem. Please try the latest
sane-frontends CVS, I have just commited the change.

Hm, as far as I know, sane-frontends doesn't use libpthred at all. Can
you try to find out where this comes from? If this is from libgtk, the
gtk-config script should take care to supply the correct libs.

Same here. gimp-config (or gimp-tool) --libs should return the correct
names. I don't think we can do anything about this in SANE, because
the name seems to change with every version (1.2.1 = 121, 1.2.2 =
122?) of gimp.

Maybe the call of sane-config --libs, gtk-config and gimp-config doesn't work with OS/2?

Bye,
