Details:

Some Octave public header files fail to compile when they are included by
themselves in a trivial C++ source file. This only affects a small minority of
Octave header files, and they are probably all headers that normal users won't
be including directly anyway.

However, I think these should probably be fixed so that headers that are
available publicly can be included and compiled.

* pt-unop.h - forward declaration of octave_value, but then tries to use
octave_value::unary_op and octave_value::unknown_unary_op

* sparse-chol.h - forward declaration of SparseComplexMatrix, but then tries
to instantiate a template specialization on SparseComplexMatrix, template
needs chol_type::element_type

* sparse-qr.h - the Complex typedef is unknown, may be trivial to solve by
including oct-cmplx.h
