The problem is in the MacOS X implementation of shared libraries (which
it inherited from NeXT).

Bash uses its own (internal) version of fnmatch(3), which has been
extended to do ksh-style `extended globbing' (shopt -s extglob),
POSIX.2-style character classes in pattern matching ([:alpha:], etc.),
and other less-important POSIX.2 features.  Other Unix shared library
implementations allow functions in an executable to override functions
with the same name found in shared libraries.  MacOS X doesn't. 

The MacOS linker doesn't complain about the redefinition, just ignores
it.

I'll probably change the name of the bash pattern matching function, but
that won't appear until bash-2.06 (or whatever I name the next release).
