CppUnit - C++ port of JUnit

Please find enclosed a patch which allows cppunit-1.12.1 to build without
warnings when using gcc-4.1 with "-ansi -W -Wall -Werror".

The patch fixes several files and deals almost entirely with unused
variable warnings (which I tend to fix through the use of anonymous
parameters) although there is also one change to call a default constructor
in an initialization list. The only really critical
patch is the one for

cppunit/include/cppunit/extensions/ExceptionTestCaseDecorator.h

which is the single public header involved.



To test the patch I did the following:

------------------------------------
$ cvs -z3 -d:pserver:anonymous@cppunit.cvs.sourceforge.net:/cvsroot/cppunit
co -P cppunit

$ cd cppunit

$ patch -p0 < ../../cppunit/cppunit-1.12.1-nowarn.patch
[...bunch of messages...]

$ ./autogen.sh
[... some messages...]

$ ./configure
[... more messages...]

$ make CXXFLAGS="-W -Wall -Werror -ansi $CXXFLAGS"
[... lots of messages...]

$ make CXXFLAGS="-W -Wall -Werror -ansi $CXXFLAGS" check
[... and even more messages ...]
------------------------------------

where the -Werror flag ensures that had there been a warning from g++ then
the compiler would have stopped there.


I changed the flags on the "make" command line, but I would have preferred
to do it in the automake/autoconf structure. Unfortunately, it wasn't
obvious how to set compiler specific flags (e.g. "if you're using g++ then
set CXXFLAGS as above, otherwise don't") and I didn't want to delay the
patch for that. Perhaps someone with more experience with the GNU
autotools can set that up.
