Interesting bug in number size determination
Sun Apr 18 14:28:00 GMT 1999
If I compile this program with -Wall:
unsigned long u;
u = 4294967295;
printf( "%lld\n", u );
u = 0xffffffff;
the compiler says:
a.c:4: warning: decimal constant is so large that it is unsigned
(this is for u = 4294967295).
Shouldn't it fit into an unsigned long?
The other interesting thing is that 0xffffffff=4294967295 and it doesn't
have problems with the hex format :)
PS: i'm not on the mailing list, please (also) reply directly, thanks.
