It would help if you provided the output from the linker so we can see
what's unresolved.  I'm a bit weary that this will work anyway.  Oracle's
OCI libraries were built using the MS Visual C++ environment.  As such,
it has references to things in the MSVCRT an expects to be run in that
environment.  I don't recall if gcc's linker can easily link with the
MSVCRT environment.  Perhaps Christopher can comment on this.
