Thanks for the report. This is fixed in the development version, and will
be in AmberTools21, which will be released soon.
It's odd that no one else has reported this (which is why we haven't
released an update patch). It used to be flagged as a warning for some
compilers, but it seems that other compilers are now issuing an error rather
than a warning, and are no longer allowing implicit declarations.
