make check broken?

[Neal Becker]

While trying out make check on linux I noticed a complaint about
unresolved symbols, caused by the pthread symbol in libstdc++ (we
already saw a patch for this).

But the complaint was about /usr/lib/libstdc++.  I think what may be
happening is that make check isn't checking the new libstdc++ in egcs, 
but the old one in /usr/lib - possibly because of the use of shared
libs.

Maybe the test programs need to be built with -rpath set to pick up
the new libraries?
