You can add #17-23 from my side :-)

Once you got Octave built completely using native MingW/MXE and have 
documented it, we might continue hunting down and weeding out unneeded 
dependencies. libodbc++/postgres/freetds and perhaps sqlite have already 
been mentioned. During MXE cross-builds on Linux I saw several other 
package names flashing by that made me wonder what purpose they would serve.

BTW last night in the qt.mk file I think I spotted a reference to 
unixodbc - but it may be implicitly unselected during configure stage so 
it may do no harm.
