I dug the problem I was having with SAFEARRAY (in addition to its being very
cumbersome to use in C++):  C++ Builder has a bug where "SAFEARRAY*" in the IDL
file is treated as "SAFEARRAY*" in the generated C++ code, when the type library
is imported;  it's supposed to be "SAFEARRAY**".  It can be worked around ...
but it's ugly.
