got_fatal_signal() fix for no sys_siglist

[Juran, James (US SSA)]

On systems without sys_siglist, got_fatal_signal() will try to convert
the signal number to a printable string.  This works, but it leaves the
variable sig modified, so that when the signal is re-raised it ends up
raising signal 0, which doesn't have the intended effect of ending the
process.

Using a different variable to do the conversion fixes this problem.  I
don't have an svn account, so if this is OK could someone please commit
it?  Please let me know if there's anything else I need to do.
