Oh, I wouldn't dream of you doing that... :)

However, I do have to point out that your reason doesn't make much  

You won't use one compiler because it has bugs which also appear in  
the one you will use.

That just makes no sense to me, but that's OK.

Run almost anything but the latest 4.x versions, and you'll see worse  
than that.

I'm just hoping that the versions I'm using now don't have it.  I ran  
some mixes of code to try and flush things like that out, and so far  
the latest compiler is much better compared to the early 4.x series.

Now if they could only solve the C++ library issue somehow...

There are other reports of it here and there if you look around.

Sun and Fujitsu made sure there was a workaround for Solaris, and  
supposedly fixed other more obscure bugs than this one, but have  
refused to tell anyone what they are.

That's one of the things I hate about GNU and to a certain extent, a  
lot of open source: no discipline.  They keep releasing a constant  
stream of new code, without ever stopping long enough to stabilize  

Only a small number of people manage to do that kind of hard work,  
and they often have to fight the other 90% of the team to do it.

Also, the compiler and a truly open C library would be better for  
getting start on the other stuff.
