Thanks a million times !

As an application developer who programmed many Linux applications,
I was not aware that I need to do that !

If I understand right from the libc manuals, I better use -D_GNU_SOURCE for
every new Linux app I develop.

Do you agree ?

I must say that I have never ever heard about it ! in years of work !
I encountered the problem only now, because I needed RECURSIVE
mutexes...
I wonder.. did this affect me in any other way before ? or even more
scary - If I begin
to use it now, will it change the behavior of my programs ?

Thanks!!!
