Backing out the updates to mingw-3.3.0 (b90033378759  & gcc 4.9.2
(eba1c6e9cbb8) made no difference.
I made a build on my other build box (using the "old" mxe-octave of late
October) and transplanted it to the "failing" box: again, no difference.

On that other box a cross-build with a fresh mxe-octave tip (8657bb199f09)
is running; when that is finished (hopefully tomorrow morning) I'll reboot
it into Win7 and try the builds made on the "failing" box.

Update:
----------
Begins to look like a tar / gzip error. 
Copying the offending c++.exe etc. verbatim from the Linux cross-build box
to Windows into some subdir and adding a few required .dlls (libstc++6.dll, 
libiconv-2.dll and libgcc_s_seh-1.dll, allow me to run them w/o start
errors.

So perhaps making a .tgz archive isn't the best solution for mxe-octave
cross-builds for Windows.
