State-Changed-Why:
    not a bug. 'false' is an integral constant expression of
    value zero i.e. a null pointer constant. This is unfortunate,
    for the reasons you give, but not wrong

>Description:
g++ from 2.95.3 and 3.0.4 allow passing a constant parameter "false" to a function with bool * parameter without complaint.  There is a complaint when true is passed rather than false:

foo.cc: In function `int main()':
foo.cc:7: passing `bool' to argument 1 of `foo(bool *)' lacks a cast

gcc-2.8.1 complains either way with the following:
foo.cc: In function `int main()':
foo.cc:7: argument passing to `bool *' from `bool'

>How-To-Repeat:
compile foo.cc with g++ from 2.8.1 and 2.95.3 to see compiler errors
>Fix:
Well, the fix is obviously to write correct code, however, it seems like the compiler should probably detect this problem.
