I do not know.  I myself am a mere supporting staff of octave for windows. 

I myself use GCC-4.4.0 of official MinGW distribution.

The make check result on GCC-4.3.0-TDM gives

   octave-3.2.2\src\data.cc  PASS  500/509  FAIL 9
   test_string.m ....................................... PASS   78/79   FAIL 1

while 

that on GCC-4.4.0-MinGW official gives

   octave-3.2.2\src\data.cc  PASS  506/509  FAIL 3
   test_string.m ....................................... PASS   78/79   FAIL 1

However, to my experience, the size of oct file witt it is about 50-70 kbyte 
larger than that by
GCC-4.3.0 TDM at using shared stdc++ library.

For GCC 4.4.0 in MinGW official, we can find

- libstdc++_s is only partially implemented.

in the gcc-4.4.0-mingw32-notes.txt.

I suppose that partially implementation gives the larger oct file size by GCC 
4.4.0 in MinGW official
than that is built gcc 4.3.0-TDM.

That is why Benjamin did not change the compiler, I think.

Note that the above is mere my guess.

Perhaps Benjamin LIndner, who is a maintainer of this release, might reply to 
your question.

Anyway the only maintainer can decide which complier is to be used. 

If you have complaint to the matter, you can build octave from source by 
yourself.
If you would like to do so, I can put my dependency libraries for GCC-4.4.0 
(MinGW  Official) to my
web site.
