Re: [PATCH 03/10] pthread_sigmask: new module

[Bruno Haible]

On FreeBSD 6.4, in a unit test that checks the signature of pthread_sigmask(),
I get a compilation error:

test-pthread_sigmask1.c:24: error: `pthread_sigmask' undeclared here (not in a 
function)
*** Error code 1

Similarly on a couple of other platforms. The reason is that the system
declares it in <pthread.h>, not <signal.h>.

This fixes it:


2011-07-07  Bruno Haible  <address@hidden>

        pthread_sigmask: Ensure declaration in <signal.h>.
        * lib/signal.in.h: On MacOS X, FreeBSD, OpenBSD, OSF/1, include
        <pthread.h>.
        * doc/posix-functions/pthread_sigmask.texi: Mention the header file
        problem.
