I did exactly the same thing as Joel said, but NO luck here.
(I debugged this issue in August 2011 for several days)

1, I build gdb under MSYS+MinGW, and the configure command has the Linux style path like:

../gdb/configure --prefix=/c/user/my-gdb

gdb can not find the python automatically.

2, I just test the official mingw-gdb (with python enabled), gdb can't relocate the "shared" path either.

3, here is what I did to check whether it works:

a, suppose you have gdb install or copied in some folder:
c:/path_to_mingw/bin/gdb.exe
c:/path_to_mingw/share/gdb/python/gdb (this folder contains some python script like:printing.py....)

b, run the gdb.exe.
b1, you can type:
python print gdb.PYTHONDIR
It should return the windows path: c:/path_to_mingw/share/gdb/python

b2, you can continue type:
info pretty-printer
Then, gdb will report all the pretty-printers installed. If you encountered some error message like:
Undefined info command: "pretty-printer". Try "help info".
This means gdb's own python script does not loaded correctly when gdb startup, this is because gdb can't find the path:
c:/path_to_mingw/share/gdb/python/gdb

So, Joel, can you just test the steps I described above? Both step a, and step b, b1, b2.

With my hacky patch I posted in this thread some days ago, my gdb.exe can works OK wherever the "path_to_mingw" put, so it is relocated.
