Changes for C++ Version 7.1 for OpenVMS I64

The following class library changes apply to C++ Version 7.1 and higher for OpenVMS I64 systems:

• The tasks and complex packages have been removed. The recommended replacements are the pthreads routines and complex template class, respectively, from the C++ standard library.
• In the String class, the char*() operator, which converts String to a pointer to char , has been removed. The String class has a const char*() operator, which can be used instead of the removed one.
