Hi, ironhead. Now, I have successfully build the gdb branch
gdb-7.0.90.20100304.tar (it takes nearlly one and half an hour), and
gdb.exe works fine, and there's no crash. thanks very much!!.
I use these build environment( MSYS, tdm-gcc4.4.1-dw2 core and g++
package, others packages like binutilites and wapi were all downloaded
from the Official Mingw sourceforge sites.)
The new build branch 0304 gdb.exe still response slowly when showing a
wxString value in watch window, but if I have not watches, it runs
fast when doing "steps or step in ...".

I use these command to build the gdb, I unzip the gdb source code in
"/c/gdb/gdbbranch20100304/" and run the scrips command in
"/c/gdb/obj/" and the generated file was installed to "/c/gdb/install"

../gdbbranch20100304/configure --prefix=/c/gdb/install --with-expat
--without-included-gettext CFLAGS="-I/c/expat/install/include -static
-L/c/expat/install/lib -O2 -w"
make
make install

As you suggested, but I have failed using the -pg option. if I use
these command:
../gdbbranch20100304/configure --prefix=/c/gdb/install --with-expat
--without-included-gettext CFLAGS="-I/c/expat/install/include -static
-L/c/expat/install/lib -O2 -w -g -pg"
make
make install

I failed in the configure step, MSYS shells just hangs when checking
the gcc system. I don't know why...
any comments?

Thanks!!!
