"--rpath" and LD_LIBRARY_PATH shouldn't be necessary on FreeBSD - the
run-time linker should be configured to search in the directory in which
libraries such as "-lgtk", "-lgdk", and "-lglib" live. On my FreeBSD
3.2 box, it is; I don't have LD_LIBRARY_PATH set, but Ethereal manages
to find those libraries in "/usr/local/lib".
For IRIX, "autoconf" should be fixed to use "-rpath" (i.e., this isn't
specific to Ethereal).

Does every system on which Ethereal can be built have "gnuc.h"? (Note
that if Ethereal requires GCC, this is arguably a deficiency....)
If I try to compile
% cat foo.c
#include "gnuc.h"
on my FreeBSD system, I get:
% gcc foo.c
foo.c:1: gnuc.h: No such file or directory
so it appears that on at least one system on which Ethereal can be
built, there's no "gnuc.h".

That's a problem with the UCD SNMP library as installed on your system;
it shouldn't require that you include "gnuc.h" - either it should avoid
using "__P()" on systems that don't provide it, or it should declare
"__P()" itself.
