Yes, but not the same as how ClamAV uses it. In this case, h_error is
a local variable, so of course the symbol resolves correctly. In real
code such as ClamAV, h_error is defined in system header files as an
external variable or a function.
That test is perfectly ok for testing how many arguments
gethostbyname_r() takes, however.
