Same for me. I just meant, that I get an annoying warning (see below) 
when doing it the right way.

Oh, oh. I hope for you, it's not the very buggy 2.95.3 from BeBits.

Same here.

Compile the first version with the usually very useful option `-
Wshadow' and you will get:

$ g++ -Wshadow tt.cpp
/tmp/tt.cpp: In function `int main()':
/tmp/tt.cpp:9: warning: declaration of `x' shadows previous local

Which is damn stupid, since it gets you a lot of warnings in perfectly 
nice code. And as someone who can't bear to get any warnings at all I 
have to turn the option off.

I can reproduce this behavior with 2.9-beos-991026 (original R5), 2.9-
beos-000224 (GG) and 2.95.3 on BeOS. GCC 2.95.3 on Solaris does this 
too, so I suppose it's a general bug.

CU, Ingo
