The egcs-c++-1.1.2-12.i386.rpm package contains (and provides) the *dynamic* library libstdc++-libc6.1-1.so.2 -- not the static one. The same library is provided by libstdc++-2.9.0-12.i386.rpm, thus the two packages conflict.
The packages don't conflict; they just share a file. Updating one should not remove the file; if it does, that's an RPM bug...
