hi,
i run NetBSD 1.6_STABLE on i386 platform, and i reinstalled
a tuned kernel and some pkgsrc such as cvsup.

the kernel has :
options         COMPAT_NOMID    # compatibility with 386BSD, BSDI, NetBSD 0.8,
options         COMPAT_09       # NetBSD 0.9,
options         COMPAT_10       # NetBSD 1.0,
options         COMPAT_11       # NetBSD 1.1,
options         COMPAT_12       # NetBSD 1.2,
options         COMPAT_13       # NetBSD 1.3,
options         COMPAT_14       # NetBSD 1.4,
options         COMPAT_15       # NetBSD 1.5,
options         COMPAT_43       # and 4.3BSD

as compat support

but when i try to exec cvsup, here is what ktrace gives me:

[...]
   267 cvsup    CALL  fcntl(0x1,0x4,0x2)
   267 cvsup    RET   fcntl 0
   267 cvsup    CALL  __sigaction14(0x1a,0xbfbfd080,0xbfbfd098)
   267 cvsup    RET   __sigaction14 0
   267 cvsup    CALL  setitimer(0x1,0xbfbfd0fc,0xbfbfd10c)
   267 cvsup    RET   setitimer 0
   267 cvsup    CALL  compat_13_sigprocmask13(0x2,0x2000000)
   267 cvsup    PSIG  SIGSYS SIG_DFL
   267 cvsup    NAMI  "cvsup.core"

as if compat_13_sigprocmask13 was not supported

has anyone a clue for me?

thank you.
