"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.
