 Hmm, this *is* the output I get on a -10'ish system
 
 $ cc -o sigmask sigmask.c
 $ ldd sigmask
 sigmask:
         -lc.12 => /usr/lib/libsparc_v8.so.0
         -lc.12 => /usr/lib/libc.so.12
 $ ./sigmask
 sigprocmask -> -1, errno=22
 pthread_sigmask -> 22
 
 
 This seems to have been fixed by kamil in response to your previous
 reprot but never pulled up.

 Adjust the error return value of pthread_sigmask for !libpthread usage
 
 Instead of returning -1, return errno on error.
 
 Catch up after the fix in libpthread by Andrew Doran in 2008
 in lib/libpthread/pthread_misc.c r.1.9.
 
 It's an open question whether this function shall be used without linked
 in the POSIX thread library.
