OpenMP #pragma omp taskwait after a label is not permitted - should fail at
compile time [Cray Bug 755983]
The test checks that the #pragma omp taskwait may not be used after a label.
Currently the GNU gcc compiler fails to produce any error message at
compile time.
The OpenMP API version 3 (May 2008) p. 68 lines 16-19 state:
"The taskwait directive may be placed only at a point where a base
language statement is allowed. The taskwait directive may not be
used in place of the statement following an if, while, do, switch,
or label."
