misc-build-cleanup-20010917

1) Removal of unused variables
2) some NT ifdef cleanup
3) use of size_t rather than int to store the result of strlen()
4) some bugs that really only occured when errors occured.
5) some functions were implicitly declared as 'int' but doing a
   "return;" Some I declared as 'void' and prototyped them; some I
   just returned a value.
