I test it again today, and it does not works on my XP.
The official MinGW-gdb is build with such configure option(like my personal build):
           CFLAGS="-O2 -fno-omit-frame-pointer -mtune=i686" \
           ../gdb-7.3.1/configure \
           --program-suffix="-python27" \
           --prefix=/mingw \
           --host=mingw32 \
           --build=mingw32 \
           --target=mingw32 \
           --with-python=/python/python \
           --with-expat

When you put the MinGW in some different folders in the driver E:
like e:/mymingw1  and e:/mymingw2

When you run gdb and enter: python print gdb.PYTHONDIR, it will always return:
e:\mingw\share\gdb/python
You see, I have no such path here in dirver e.
I'm not sure how you test your gdb, did you just put you MinGW under e:/MinGW? Can you try some other places?

If you don't have any pretty-printers installed, but gdb's own python script loaded correctly.
you will have nothing returned from gdb, like:
(gdb) info pretty-printer [ENTER HERE]
(gdb)
