Fix compiler warning in config assert() on 64 bit architecture (#158)
Fix compiler warning in config assert() on 64 bit architecture (#158)

* Replace the following code that was used to force an assert:
configASSERT( pxTCB->ulNotifiedValue[ uxIndexToNotify ] == ~0UL );

with:
configASSERT( xTickCount == ( TickType_t ) 0 );

Because the former generates a warning on 64-bit architectures.
