sigset, sighold

[Johan Pettersson <johpe159@student.liu.se>]

Hi!

I am trying to compile a simple program. I know
it works under UNIX and now I will run it under linux.
But it say :undefined reference to 'sigset', 'sighold'
when I try to compile it! In which headerfile can I find
them ? Or do I need something else ?
