Pb with signal and read

[Christophe Leroy]

Hello,

I'm using gcc on Linux RedHat 6.2
It's said in man that signal() behaviour is SYSV one. But, when I
compile my programs, signal() has got the BSD behaviour. Why ?
How can I make it have SYSV behaviour ?

read() doesn't return on signal. Why ? I want it to return with
errno=EINTR. How can I do that ?

Thanks

Christophe
