configure's test is purely a linker test. It does not check to see
where/whether the function is declared. Meanwhile, the compiler is
complaining that it doesn't see a declaration. So the problem
probably can be fixed by adding an #include, but you'll need to
figure out what.

I see that our other user of inet_pton, fe-secure-openssl.c,
has a rather different #include setup than fe-secure-common.c;
does it compile OK?
