Odd.  That database and that code work fine on so many other platforms.

The UDUNITS lexical scanner knows about the "%" sign and correctly
treats it as a token.

You shouldn't get the "Replacing unit ..." messages.

I don't know why your system is misbehaving.  We have a J90 system at
NCAR.  When I get some time, I'll see about testing the UDUNITS package
on it.  Otherwise, the only thing I can suggest is recompiling the
package with debugging enabled and using a debugger to locate the cause
of the above messages.
