[jphickey]

Describe the bug
When compiling the test app under RTEMS, a build failure occurs:

/home/joe/code/cfecfs/github/cfe/modules/cfe_testcase/src/es_task_test.c: In function 'TestCreateChild':
/home/joe/code/cfecfs/github/cfe/modules/cfe_testcase/src/es_task_test.c:89:5: error: format '%d' expects argument of type 'int', but argument 7 has type 'uint32' [-Werror=format=]
     UtAssert_True(countCopy == count || countCopy == count + 1, "countCopy (%d) == count (%d)", countCopy, count);
     ^

To Reproduce
