This is weird.  What kind of shell does Minix have?  Maybe it doesn't
understand the `!' as negation in patterns?  Hmm,
http://www.minix3.org/manpages/man1/ash.1.html lists it as documented.

Could you show the trace of such a failing command?  Either with
  .../libtool --debug [ARGS]

or with
  $SHELL -x .../libtool [ARGS]

(be sure to ask the package-specific libtool script rather than the
globally installed one, if any).  Which libtool version is this by the
way?

The pattern
  *[!-_A-Za-z0-9,/]*

should match anything containing a character not alphanumeric, nor
comma, slash, underscore, minus.  If that is not the case for your
shell, I'm inclined to say that this is a shell bug.  (Note this is
valid in the C locale only, generally)

In any case, Libtool has not been ported explicitly to Minix AFAIK.
This means, that the building of static libraries should work, but
if Minix has a form of shared libraries (which I don't know if it
does), then Libtool would need to be added explicit support for it.
If you intend to port Libtool, or would like help in doing so, you're
welcome to write to bug-libtool at gnu.org.

Cheers,
Ralf
