extern char const allsigstr[];
This would consist of a concatenation of null-terminated strings,
one per name, terminated by an empty string.

I seem to recall a paper several years back that argued against this
approach based on ldso issues. Drat, can't dredge the details...
I tried searching the Internet for such issues, but couldn't find any.
What do you recall as being the loader problem? The "extern" part? Or
use of a null string for termination?
I'm just thinking, Paul, if the null termination/index pointer idea were
used throughout the string array, one could continue to use the
int sig2str (int, char *);
function in a backward compatible way.
What was I thinking? That wouldn't be backward compatible. sig2str is
copying onto the passed into character string pointer.
