Hi, Tom, After struggling with the building gdb, I finally found a very 
strange build problem.

under MSYS and MinGW 4.4.5.

Today, I can build the gdb source from the snapshot: 
gdb-7.2.50.20101213.tar.bz2
I have already released in the codeblocks' forum post:

http://forums.codeblocks.org/index.php/topic,11301.0.html


But the real strange thing is: I failed build the gdb from the git 
working copy.
The error is just like the same as I reported several days ago. that is:
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

I have both a folder named "gdb" (this is the git working copy)
and a folder named "gdb-7.2.50.20101213" (this is unzipped snapshot)

Then this command works:

cd build
../gdb-7.2.50.20101213/configure --prefix=/E/test/install 
--build=mingw32 --host=mingw32 --target=mingw32 \
    CFLAGS="-s -L/python/libs -I/python/include 
-I/E/test/expat/install/include -static -L/E/test/expat/install/lib" \
    --with-python \
    --with-expat
make
---------------------------------------------------------------------------------

But this command failed with the error I shown above:

cd build
../gdb/configure --prefix=/E/test/install --build=mingw32 --host=mingw32 
--target=mingw32 \
    CFLAGS="-s -L/python/libs -I/python/include 
-I/E/test/expat/install/include -static -L/E/test/expat/install/lib" \
    --with-python \
    --with-expat
make

----------------------------------------------------------------------------------

by the way, the gdb git address I'm using is:

git clone git://sourceware.org/git/gdb.git

list here:

http://www.gnu.org/software/gdb/current/

Any ideas?

thanks.
