In fact, programmingkid, you should fix it in hdev_open() where there is
already a #if __APPLE__ .
Paolo, I agree with you but :
hdev_open()
#if defined(__linux__)
{
char resolved_path[ MAXPATHLEN ], *temp;
temp = realpath(filename, resolved_path);
if (temp && strstart(temp, "/dev/sg", NULL)) {
bs->sg = 1;
}
#endif
