The last working version is a00379f6f8c4 (fminsearch.m: Accept problem 
structure for Matlab compatibility).

Changesets 332be8be16eb thru 56ac36b5f7b0 are unable to build __init_qt__.la.

56ac36b5f7b0: eliminate unnecessary use of this-> in member function

        clang: error: linker command failed with exit code 1 (use -v to see 
invocation)
        make[2]: *** [libgui/graphics/__init_qt__.la] Error 1

Changeset 14e844f1459a fixes the __init_qt__.la build problem.

14e844f1459a: fix linking of __init_qt__.la on Windows systems (bug #54881)

After fixing this problem, when the qt toolkit is used, Octave seg-faults when 
exiting.

        fatal: caught signal Segmentation fault: 11 -- stopping myself...
        make[2]: *** [doc/interpreter/convhull.txt] Segmentation fault: 11
        make[2]: *** Deleting file `doc/interpreter/convhull.txt’

Speculation on my part, but this may be related to the problem with cleaning up 
qt before exiting.
