Subject: signal: fix warning in older compilers.

* signal.c (sig_handler): Some older compilers cannot figure
out that stack_lim is not used uninitialized, due to the
conditional logic here, in which two separate code blocks are
guarded by the same condition. Let's initialize the variable,
like the others.
