pthread_delay_np() parm compile error on AIX

[Kevin Burge <kevin.burge@…>]

On AIX 7, pthread_delay_np is declared as:

extern int pthread_delay_np ((struct timespec *));

Compilation fails with: === vacpp.compile.c++ bin.v2/libs/thread/build/vacpp/release/address-model-32/threading-multi/pthread/thread.o "libs/thread/src/pthread/thread.cpp", line 439.48: 1540-0256 (S) A parameter of type "timespec *" cannot be initialized with an expression of type "const timespec *". "libs/thread/src/pthread/thread.cpp", line 439.48: 1540-1205 (I) The error occurred while converting to parameter 1 of "pthread_delay_np(timespec *)". ===

It appears that there is a bug related to this, #78.

Compiled fine with 1.52.0.

Would the following patch solve the issue?

+  #     if defined(__IBMCPP__)
+                BOOST_VERIFY(!pthread_delay_np(const_cast<timespec*>(&ts)));
+  #     else
                 BOOST_VERIFY(!pthread_delay_np(&ts));
+  #     endif

The patch resolves the compilation error. I did not test the behavior, though. Thank you!
