OK, this looks like an incompatibility between the C compiler and
glibc shipped with RedHat 9.  There is more about the issue here:

    http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=86465

including some suggested fixes.  For instance, the following short C
file can be compiled and added to the Runtime.a archive, to resolve
the deprecated __ctype_b symbol to the new __ctype_b_loc version.

Regards,
    Malcolm
