extensions to ANSI C are disabled if they may cause strictly conforming programs not to compile, or to work differently if those extensions are enabled. (Other compilers #define it as 0, e.g. Sun's and, I think, other AT&T-derived compilers; still others cheerfully define it as 1 even when those extensions are enabled, e.g. GCC.) As such, checking whether __STDC__ is defined, or is defined as a non-zero value, isn't the right way to check whether function prototypes are supported; MSVC++ 6.0 supports them, but, by default, leaves extensions of the sort described above enabled, and thus doesn't define __STDC__. This means that the compiler warns about arguments to "snprintf()" when compiling it, as the declaration is an old-style declaration. As Ethereal uses function prototypes, there's not much point in making it possible for its private "snprintf()" to be compiled or used when function prototypes aren't supported; just get rid of the tests for __STDC__, so that it's compiled with function prototypes regardless of whether __STDC__ is defined or not. While we're at it, have "snprintf()" give it a "__attribute__((format (printf, 3, 4))))" when compiled by GCC 2.x or later, so that format/argument checks can be done even on platforms lacking "snprintf()". svn path=/trunk/; revision=2689
