I have answered in you last thread, please check the mail.=0A=
=0A=
Yes, but for some reason, it was not include, see /usr/include/signal.h:358=
=0A=
=0A=
# include <bits/sigstack.h>=0A=
# if defined __USE_XOPEN || defined __USE_XOPEN2K8=0A=
/* This will define `ucontext_t' and `mcontext_t'.  */=0A=
#  include <sys/ucontext.h>=0A=
# endif=0A=
=0A=
So only if __USE_XOPEN or __USE_XOPEN2K8 been defined will include =0A=
<sys/ucontext.h>=0A=
=0A=
=0A=
Why NAK?=0A=
=0A=
Thanks,=0A=
