While that will allow it to compile, it will still produce incorrect
output (zeroes where it should produce nulls).

If you're going to the trouble of manually editing that file, you may
as well fix the bug at the same time, by changing the line:

	if(isnan(vis[col]) || isnan(alt[col]) || isnan(buf[col])) {buf[col] = FP_NAN; continue;}

to the code used in 6.4 and 7.0:

	if(vis && G_is_f_null_value(&vis[col]) || 
	   alt && G_is_f_null_value(&alt[col]) || 
	          G_is_f_null_value(&buf[col]))
	{
	    G_set_f_null_value(&buf[col], 1);
	    continue;
	}
