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.
