[sr #107522] Use of dangerous/banned functions

[Jeffrey Walton]

Follow-up Comment #2, sr #107522 (project gnutls):

It occurred to me: use of unsafe functions are still at pandemic proportions,
yet I don't recall ever seeing a GCC warning.

Doing something about it: "Request: Warning for use of unsafe string handling
functions", http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46513.

Mircosoft's tool chain emits warnings on their use, and SAL (/analyze) takes
its a step further by offering abuse scenarios (for example, "readable size is
4 bytes, but 16 bytes might be read").
