Thanks for the followup, Paul.  I know the problem with g++ binaries
pretty well - I've stumbled across it before.  Thanks for pointing
that out to me.  I'm a little confused about how to pass the
appropriate LDFLAGS to the test harness, though.  Here's what I did:

  1. ../../src/bison-1.875d/configure '--prefix=/usr/local'
     '--disable-nls' LDFLAGS="-R$USRLOCAL/gcc/lib"
  2. make
  3. cd tests
  4. /bin/sh ../../../src/bison-1.875d/tests/testsuite 43
==> 
ERROR: 1 test was run,
1 failed unexpectedly.
  5. ldd testsuite.dir/043/input
==>
        libstdc++.so.6 => not found
        libm.so.6 => /lib/i686/libm.so.6 (0x40024000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40046000)
        libc.so.6 => /lib/i686/libc.so.6 (0x4004f000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

libstdc++.so.6 lives in /usr/local/gcc/lib, so what's the problem?
How do I pass LDFLAGS to the testsuite?

Thanks,
  Vin
