Removed CFront 1.2 -specific code from skeleton, because CFront now defines __cplusplus properly.

Removed TurboC-specific code from skeleton.
Skeleton now includes proper C++ standard headers.
Relocated "unistd.h" code after user section 1 to allow user to overrid it.
New option "nounistd" to suppress unistd.h from being included.
