I would be interrested in finding out what's the difference between 
v2.95 and v2.95.1 which is already on our local GNU mirror
(source codes, not DJGPP binaries!!!).

Yesterday I had some discussions with a colleague about v2.95 and 
he was very disappointed (although he used a different wording 
which I'm not going to repeat here in the NG).

He is working on a C++ program that computes a sequence of 
binary numbers e.g., 100111011... (don't ask me for details,
I don't know). The program used to compile and run on a number
of unix systems both with native and GCC (2.8.1) and also DJGPP
and had equal results.
Now with GCC v2.95 he is getting different sequences of 1 and 0
depending on the level of Optimization. I don't remember exactly
but I think he said the one matching the previous output is not
from the -O2 compiled binary. We have reproduced this effect on
DJGPP, Linux and Solaris running GCC v2.95.
