--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, gcc is silent even with -Wc++-compat added! 

$ /usr/local/bin/gcc -c -Wall -Wextra -Wconversion -Wc++-compat 55096.c
$

What's worse is that with g++, the -Wconversion-null warning is now an error:

$ /usr/local/bin/g++ -c -Wall -Wextra -Wconversion 55096.c
55096.c: In function ‘bool* ProcessRequest(bool*)’:
55096.c:5:17: error: cannot convert ‘bool’ to ‘bool*’ in assignment
   charge_acct = false;
                 ^~~~~
$

So this means that this is also an issue of -Wc++-compat failing to catch
something that would be an error in C++.
