If that is true, why cannot egcs 1.0.3 and 1.1.1 co-exist? If you take
a closer look at my library interface, you will see it supports N
different C++ compilers/libraries by

1. Put

libstdc++-$(LIBSTDCXX_INTERFACE)$(LIBC_INTERFACE)$(CXX_INTERFACE)-$(VERSION)

in $(prefix)/lib.

2. Put symlinks of libstdc++.so and libstdc++.a in the compiler
directory.

It is how my library interface works. We just need to retrofit the
egcs 1.0.3 binaries to get it to work. The key to solve the RedHat
problem is (2). Did I miss something?
