Log:
 Add some additional arguments to AC_WIRESHARK_GCC_CFLAGS_CHECK() to make
 it do an additional check, if it finds that a given compiler option is
 supported by the compiler, to see whether it's supported but
 undesirable.  The arguments are a chunk of code to try to compile with
 -Werror, and a string to be used in the "checking..." message printed
 when trying to compile the cunk of code.
 
 Try enabling -Wshadow again, but have it check whether
 
 	extern int atoi(char *p);
 
 	int
 	foo(char *p)
 	{
 		int (*fptr)(char *p) = atoi;
 
 		return fptr(p) * 2;
 	}
 
 compiles with -Wshadow and -Werror, so that we don't use -Wshadow with
 compilers that complain about that; some older versions of GCC complain
 about that, and it's really not worth our effort to eliminate or rename
 arguments in function prototypes to make -Wshadow work even with those
 compilers.
