Hi,

Attached is a patch to let guest programs use SIGRTMIN + 1 by swapping with
SIGRTMAX - 1. Since QEMU links against glibc, it reserves the signal for
itself and returns EINVAL (as noted in the commit message). This means
various applications that use SIGRTMIN + 1 cannot run on QEMU, including
G-WAN web server and Open TFTP.

Thanks,
Marli
