[Bug-gnucap] Compiler errors

[Steve Little]

Hi,
        I just downloaded gnucap and get quite a few compiler errors
on cygwin, g++ v3.4.4. Attached is a patch to clean them up.

In short, there were a few problems where the keyword 'typename' was
required to clear up some ambiguities, and I needed to make copy
consturctor for CPOLY1 non-explicit (presumably because g++ chose not
to elide the extra copy when calling:

FPOLY1(CPOLY1(a,b,c));

this was causing an error since it couldn't implicitly call the copy
constuctor. I don't see any real harm in the copy constructor being
implicit, so should be fine.

I've run the examples (in batch mode) using examples/runall, and they
look fine (with a minor difference in the last test, possibly the
example output is out of date? i notice the version numbers are out of
date on it...)

I haven't had much chance to try the application yet, but it looks promising.

Thanks,

Steve
