libstdc++ testing using DejaGnu

Recently I downloaded GCC 3.3.2 and ran the libstdc++ tests. I've
observed the number of libstdc++ tests have increased about 450%! I
have some questions regarding the new testsuite which use the DejaGnu
test harness.
1) What is the libstc++ testsuite code coverage? What are the goals? The
LSB has calculated that there are about 3602 C++ ABIs.

2) Is there an easy way to build the tests so the binary images can be
packaged up to run on other machines? I would like to run the same
binary images on a various systems to help prove binary compatibility.
2b) In /usr/share/dejagnu/dg.exp I wanted to pass -keep-output to
dg-test, but I could not figure it out so I hard coded it. :-)

global srcdir ;# eg: /calvin/dje/build/gcc/./testsuite/

set i 0
if { [string index [lindex $args 0] 0] == "-" } {

2c) The above "keep" hack kept dejagnu from removing the runtime images;
however, the object files are left in the toplevel directory and many of
the test files have the same name, so a large number of the images are
overwritten and lost. So what I did was rename all of the test
filenames, then rebuilt and reran the tests.
find * -name "*.cc" -print | while read file; do
new=$(echo $file | sed -e 's/\//_/g')
dir=$(dirname $file)
cp $file $dir/keep-$new
done
3) How can I get DejaGnu to run binary images that I have created above
and not try to build the tests from source?
