[ns] Nam compile problem on RH6.2

[Andrei Gurtov <gurtov@cs.Helsinki.FI>]

Hi,

 While installing all-in-one-latest NS package on RedHat Linux 6.2 there
was a small problem with linking of Nam. It required __rethrow function
which does not seem to be available in libgcc.a of gcc version
egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) supplied with RH6.2.
Grabbing libgcc.a version 2.95.2 and linking it (in addition to the
original libgcc.a) to nam helped. Nam seems to work fine after that.
