GDB troubles on Windows x64

[rean]

Hi!

I installed Windows x64 to develop native x64 applications using C::B and Platform SDK.
All compilers from PSDK work correctly and C::B works fine, but it cannot debug
GCC-based applications.

The log is:

> directory D:/Dev/empty/prj/
> file ../bin/x86-gcc-deb.exe
> cd ../bin
> delete
> set confirm off
> set disassembly-flavor intel
> run

Error: dll starting at 0x78d41000 not found.
frames-invalid

Than it crashes.

It is very strange, because I can use GDB in command line mode or over Insight
without any problem.

I tryed C::B with Mingw included with new GDB, but it cannot work, too.

Please help.
