[Bug c/34710] FORTIFY_SOURCE matches to many patterns

------- Comment #5 from graeme at argyllcms dot com  2008-02-09 00:04 -------
The code is not "buggy". printf and fprintf are not reserved words, and
occupy a separate namespace with regard to the structure name and any
global function names. Because macros are a pre-process and don't understand
the language syntax, they don't respect the difference in namespace
and are therefore inherently dangerous and not guaranteed to work as
a mechanism to change the number of arguments to a function.

Ideally FORTIFY_SOURCE should use some other mechanism
that does respect the name spaces.
