difference in int,long behavior in gcc-3.4 4.0 vs 4.1 4.2

[Oleg Verych]

Hallo.

I have question about `int' silently becoming `long' in 4.1 and 4.2
GCC on AMD64.

`For' loop gets infinity on 3.4, 4.0 due to

int i; // ssize_t => signed long bar; amd64

for (i=0;i<bar;i+=2)...

4.1 and 4.2 are fine!

It's swab() in the dietlibc with at least two bugs, but this one is worth
asking here.

Test, code, compile switches and discussion are here:
