[svn-r9786] Purpose:
bug fix and document. Description: Unix and probably other systems too, has a small exit value range such as 1 byte. So, exit(256) may end up the same as exit(1). Added caution message to the exit wrappers and changed test programs to exit(1) when errors detected. Platforms tested: tested in copper. verified here that exit(256) was treated just like exit(0).
