build fix under solaris based oses :

[devnexen]

• "Initialiser in not constant". related to the pthread barrier conf field.
• Initialising it in main instead.

[deweerdt]

I can't reproduce the issue with Solaris 11 and gcc 4.8.2, which compiler were you using?

[devnexen]

openindiana and gcc-4.4.4

[devnexen]

In fact I "trickered" by changing one header file in libyrcmds to detect properly the operating system (change merged in the related github project now), and this change to make it work.

[deweerdt]

The change looks good to me. I suspect that the compiler balks at initializing struct members. If we used c99, we could use named initializers to make the issue go away (since POSIX mandates that SIZE_MAX, PTHREAD_MUTEX_INITIALIZER, and PTHREAD_COND_INITIALIZER all be constant suitable for static initialization).

Thank you for the fix!
