on an unsigned type which does a < compareison.
std::numeric_limits <signed long>::digits on a 32bit FBSD will yield 31 because its
got 31 bits for magnitude.
Unfortunately the way it seems to go about calculating that stuff at compile time
seems to be invalid due to the fact that it does < 0 compares on unsigned types.
Is this a gcc issue or a FBSD issue? [is this the original gcc c++ header file or has
it been tweaked?]

Hi,
If I compile the following program:
#include <iostream> int main(int argc, char *argv[] { return 0; }
with the following flags:
g++ -W -Wall b.cc
I get lots of warnings that did not appear in GCC 3.2:

Is there a way to fix the <limits> header file?
