Oh, absolutely.  I am documenting things as I go along.
I've got a goodly-sized notebook going.  :)

Agreed.  I'm just wanting to get things working at the moment.
I figure we can edit some to brings things into an acceptable
state.

One issue I've discovered is that our vedor's parser chokes on
some of the template code in basic_string.h.  Because the
template declaration specifies _Alloc as a parameter (typedef'd
to allocator_type in the class) and _Alloc also exists as a
member of std::allocator<>, the parser gets confused at the
declaration of _Alloc_hider, thinking that the "const _Alloc &"
parameter in the ctor is an access to the (private)
std::allocator::_Alloc since the template is instantiated with
_Alloc=std::allocator<>.

I believe this is a bug in the parser and I'm going to notify the
vendor.  In the meantime, adding more #ifdef's (yep, they'll be
cleaned up) and changing _Alloc to allocator_type solved the
problem.  I'm sure I'll run into more of these.

Good.  I am flying blind, but I'm pretty used to it at this point.

Always.
