Description Sir Raorn 2002-10-03 16:14:52 MSD

This is gcc bug #7808 (<a href="http://gcc.gnu.org/cgi-bin/gnatsweb.pl?database=gcc">http://gcc.gnu.org/cgi-bin/gnatsweb.pl?database=gcc</a>) reported and closed by Nicola Pero &lt;nicola AT brainstorm DOT co DOT uk&gt;

The compiler seems to be ignoring casts from \'id&lt;Protocol&gt;\'
to \'id\', and from \'id&lt;Protocol1&gt;\' to \'id&lt;Protocol2&gt;\'.

It\'s a regression: previous compilers (eg 2.95 and 2.91.66)
did the cast properly.

This bug fixed in upstream version 3.3 and test code from GCC's Bugzilla works
with mingw32-gcc-3.3-alt1 crosscompiler.
