It fails to build on IRIX 5.3 due to missing siginterrupt function:

Since gnulib does not provide a siginterrupt replacement I instead added
the replacement used by bash 4.0 to tests.c:
Thanks for the report, I believe this should be fixed in gnulib.
I'm not so sure. POSIX lists siginterrupt as obsolete (in other
words, the better action would be fixing your code to comply
to modern POSIX, rather than making it easy to rely on a
crutch for using an obsolete interface, similar to how we
recommend memset over bzero).
Oh. I didn't notice that. There is a slight difference though, since
siginterrupt is still part of POSIX but bzero is not.
However, I share your concern, and no longer feel it is important to
push this into gnulib. I'm going to fix my code to use sigaction
instead.
I noticed my code does something like this:
#ifndef _WIN32
old = siginterrupt (SIGALRM, 1);
alarm (secs);
#else
setsockopt ((int) gnutls_transport_get_ptr (session), SOL_SOCKET,
SO_RCVTIMEO, (char *)&secs, sizeof (int));
#endif
I'm thinking that using setsockopt may be more elegant than using a
SIGALRM signal, but I'm not sure. Any advice?
Solaris and HP-UX do not support SO_RCVTIMEO, unfortunately, according to
