I helped getting it working for XEmacs. Nevertheless I've seen another message that the fix I've send is not optimal (should crash if MALLOC_CHECK_ is set) and therefore shouldn't be applied. I'll keep you updated. Jan > From glancing at the patch in its current incarnation, Jan> it seems awfully glibc specific to me. If I understand it correctly.

Solaris doesn't use doug lea malloc - or has somebody added general support for it in XEmacs in the meantime? Jan> P.S. Why does Glibc 2.1.x define I_SETSIG ? AFAIK because it's part of the required interface of <stropts.h> - but all stream functions set errno to ENOSYS. If you think this is a bug, send a bugreport via glibcbug or the www interface at <http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl>;.
