nt/INSTALL is intended for the released version of Emacs, where this
step is unnecessary.  CVS users are expected to either read
INSTALL-CVS or cope with it when they get that error the first time
they build from CVS. Subsequent builds will not require a make
bootstrap (but you'll need to "make recompile" in the lisp subdir to
generate any new .elc files).

The intent is to assume that it is available and try to build the
info files.  It is only an issue for CVS users, so it is not too much
to expect them to be able to install it.  Configure tests are
difficult to get right on Windows, because of the variety of shells
that need to be catered for.

Can one of you try to investigate, perhaps by disabling optimization
options one by one (I think we use -O2, but it is possible to have
finer control).  Once we narrow down the type of optimization that is
causing this, it may become apparent what sort of problem to look for.
The MS compiler I have does not do optimization, so I cannot debug this
directly myself.
