We got one end May / beginning of June '96. Fortunately, we were
able to help the guy with telling him to "SAVE", i.e. "make static"
in C-speak, a handful of variables.
However, the general problem had already been brought to the
attention of the gcc2 mailing list on the 24th of February '96 by
Robert Dewar (dewar@gnat.com)
