The header files on my machine only define tmpnam_r in
case __USE_MISC is true. The latter is defined for either
BSD or SysV compatibility, yet not by _XOPEN_SOURCE.

I guess we should patch signalmodule.c to fall back to _NSIG
instead of trying SIGMAX.

I'll check in a fix later today.

Same errors.
