Of course. Discussing issues (like for the instantiation case) is of
great help. Most of the issues above are fixed or worked around. I'm
currently recompiling octave and will post a full patch for discussion
when it's done.

However, at the moment, compilation fails in CmplxQR.cc, in the
for-loop starting at line 324. Full error is given below, but it seems
MSVC promote volatile octave_idx_type + octave_idx_type to
volatile octave_idx_type, and fails to:
1) resolve the ambiguity in instantiating std::min
2) use a volatile octave_idx_type as argument for const octave_idx_type&

What's the reason of declaring "i" volatile in this case?

Michael.
