They were made to support libc_r on ia64. In the past weeks I made libthr the primary (and currently only) threading library on ia64, but the "old" libc_r.so.5 still exists and can be used by threaded programs not relinked after I made libthr the primary library. By removing the support in setjmp()/longjmp() for context switching, those threaded programs will fail. Please make sure to relink any existing libc_r based threaded applications before upgrading. The support will be removed in the coming days. For those interested in KSE: there's a complication with the context. More specifically: contexts created by the kernel are invalid. It's being addressed. FYI, -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
