But it should only do this, when LD_RUN_PATH is not set, since
unfortunately -R cancels the settings from LD_RUN_PATH. So when
LD_RUN_PATH is set (and -R is not present) /path/to/libstdc++ should be
added to LD_RUN_PATH. 

I think it should be the default. When I installed the shared libg++, I
got a lot of complaints from our users asking why their programs did no
longer run. The tenor was, that for getting an executable it should be
sufficient to say "c++ -o program part1.cc part2.cc ... partx.cc" like god
has it intended to be :-), without the requirement for funny options
nobody ever heard of. Eventually I made a little shellscript and called it
g++, which adds /usr/local/gnu/lib to LD_RUN_PATH if it is set or else
adds -R /usr/local/gnu/lib and then calls g++.real. But it would be great
when g++ could handle it per default (and perhaps configurable via
specs...)

Just my 2 cents
