signal.h

[Anton Bossenbroek]

Hello everyone,

I am puzzled my a problem which arises when using the autobuild tools  
on Linux. I try to compile a simple program which uses signal.h  
(sigemptyset(3), sigaction(2)). On Mac OS X I encounter no  
difficulties (autoconf 2.59, automake 1.6.3, Mac OS 10.4.2), but when  
I try this on a Linux system (fedora and gentoo, automake 1.6.3,  
1.9.6, 1.9.2, autoconf 2.59) gcc reports errors which are related to  
definitions in the signal.h header. When I try to compile by hand,  
everything works fine. Could someone help me out on this? If you need  
the full source I can send it.

Thanks for your answers,

Kind regards,

Anton Bossenbroek
