"copy_n" is a function that is supplied with some versions of STL but not
others. I thought all Linux versions used the GNU STL, which did supply it.
In 0.31 and earlier, you need to #define NEEDS_COPY_N in the Makefile
(Make2.g++).
You should not see this problem with 0.32, because it (supposedly) is fixed
to never use the questionable STL copy_n.
The confugure script should take care of this, but doesn't. It should be a
non-issue in 0.32, but is in earlier versions.

The default arguments are given twice. To fix, remove them from
u_xprobe.cc:29. It is not a problem on older versions of g++, and will be
fixed in 0.33. Thanks.

That's the intent. Sometimes there are bugs. Thanks for the bug report.
Version 0.32 is available from
ftp://progeny.isu.edu/pub/gnucap/gnucap-0.32.tar.gz . It should appear on
the gnu and geda sites soon. There are some other documents, including
papers and presentations, at progeny.isu.edu that may be of interest.
