Feel free to do so, I don't expect any problems on other platforms.
However, make sure you try this first by renaming the epan/config.h
into epan/config_unused.h and then try compiling Ethereal. Reason for
this is that <config.h> with -I. -I.. will first include the config.h
in epan...

There's another reason why we get those duplicate linkages: today
we're using the autotools to add stuff directly into CFLAGS, INCLUDES
and LDFLAGS. A better approach is to define CFLAGS etc per target by
using configure substitution, something like:
# Makefile.am excerpt
libethereal_la_CFLAGS = @CFLAGS@ @PCRE_CFLAGS@ @KRB5_CFLAGS@ ...
libethereal_la_LDADD = ...
To me it doesn't make sense to add all library stuff into the global
CFLAGS.
