Nahhhh... sorry it took a bit of time before your previous post's 
contents dawned on me. Must have been a busy day today for me:-)

Simply copying the relevant Qt4 libs QtCore4.dll, QtCore4d.dll, 
QtNetwork4.dll, QtNetwork4d.dll, QtGui4.dll and QtGui4d.dll and 
stripping them from the trailing '4' sufficed. Perhaps some more libs 
may need this treatment to fix some glitches I see in the GUI.

Results of "make check":

Summary:

  PASS     10475
  FAIL        10
  XFAIL        4
  SKIPPED     11

..and there are several "permission denied" tests 
("X:\programs\msys\home\Philip\octdev\oct-3.7\..\octave\scripts\special-matrix/date.m: 
Permission denied"), I'll look into that.
Failed tests:
- mappers.cc: assert (isprint (charset), result) differs in column 10. 
\r\n versus \n line endings?
- data.cc: the usual (for MinGW) NaN vs Inf issue
- file-io.cc: locale issue with fr_FR (also known on at least MinGW)
- num2str ("known failure")
- doc.m (hmmm, I built with --enable-docs=no)
- imread.m (also known on MinGW)
- copyobj.m: <cannot find magic.mgk issue. Known on MinGW>
- ishghandle.m: "imread: cannot find default.img"
- residue.m: dimension mismatch (IIRC also known on MinGW)
- speed.m: "All running times were zero" both tests
- test_system: umask doesn't match Windows file system
Most of these failed tests do not look very serious. I'll see if I can 
fix some of them.

A screenshot of the MinGW GUI as it stands is attached (from 
./run-octave in <BUILDDIR>.
A few first observations:

- Missing icons on toolbars (they do show up on the Linux version)

- The Welcome screen comes up in an endless loop. The file 
"<SRCDIR>/libgui/default-qt-settings" first must be copied to 
%USERPROFILE%/.config/octave/qt-settings before the GUI picks up (bug 
#37161)

- Octave complains about: "QObject::startTimer: timers cannot be started 
from another thread" (2X)

- Initially the terminal is only a few (15? 20?) columns wide. Only 
after changing font the full terminal width is used. I also saw that on 
the 3.6.2 MSVC GUI snapshot.

- Terminal is white text-on-black background. That gives me a headache 
after a while, how can I change that? On Linux it is black-on-white by 
default.

- Tab widths and tab order in the Workspace, Current Directory and 
Command History panel aren't preserved. A bit clumsy, hopefully that can 
be fixed in the future.

Anyway: Thanks for helping to compile 3.7.0+ on MinGW!
