Hello gnulib folks,
Please consider placing extern "C" around the sig2str and str2sig
declarations inside sig2str.h similar to the attached diff/changeset.
We're looking at using the sig2str routine in Octave and removing some
code from that project that is similar to what sig2str but not
up-to-date with all the Unix SIG definitions that might exist.
I would also like you to consider the issue of duplicate signal
definitions (i.e., different SIGxxxx using the same number such as
SIGCHLD and SIGCLD). Right now, sig2str will return only one string
associated with the signal number (first appearance) even though
internally the structure numname[] contains a complete list. If someone
wants to know all definitions, then sig2str doesn't really indicate
that. What do people think? Should there be a routine that provides a
complete listing?
Thank you,
Dan

Encase signal information functions inside extern "C" qualifier.

conditioned on __cplusplus being defined.
