Subscribe to the djgpp-announce list to receive announcements about newly
DJGPP packages and other software. See http://www.delorie.com/djgpp/ .

The packages I have for gcc 2.95.3 are dated March 30th 2001. The alpha
packages I have for gcc 3.0 are dated May 24th 2001 (see v2gnu/alphas/ in
the DJGPP archive on Simtel.NET).

This bug is quite subtle, which is perhaps why it has slipped through the
net. All software has bugs - deal with it. Actually I would expect a third
category of bugs - undetected bugs in existing functionality.

Have you constructed a test case that exhibits the bug and reported it to
the GCC maintainers? (I must admit that I have not - I got distracted by
bugfixing my own software. ;) )

Bye,
