[irrtoolset]Making IRRToolSet compile...

Hi,

me again.  Someone pointed me towards IRRToolSet which is a bit
newer than RAToolSet.  I'm trying to make IRRToolSet 4.8.1
compile on NetBSD 1.6 with gcc 2.95.3 and the libsdc++ which came
with that compiler.

First off: it seems that almost all of the diffs I sent earlier
against RAToolSet still have to be applied to IRRToolSet.

Second: how has anyone got IRRToolSet 4.8.1 to compile?!?  I have
to ask, because I get:

c++ -c -I/usr/pkg/include -I/usr/X11R6/include -O2 -I/usr/pkg/include -I/usr/X11R6/include -DHAVE_CONFIG_H -I. -I. -I.. -I../src -I../../Core  prefix.cc
prefix.cc: In method `void MPPrefixRanges::and(MPPrefixRanges *)':
prefix.cc:1147: implicit declaration of function `int assign(...)'
gmake[4]: *** [prefix.o] Error 1
gmake[4]: Leaving directory `/usr/pkgsrc/net/IRRToolSet/work/IRRToolSet-4.8.1/src/rpsl/rpsl'

...and implicit declarations in C++ are as far as I know fatal.
How can this compile at all on any other platform?

Fixing this appears to require more C++ skills or familiarity
with the code than I have, so assistance on this point would be
much appreciated.

Regards,
