Simply skipping PATH settings, cmdproxy.exe continues normally after
quitting c:\msys64\mingw64\bin\gdb.exe(full path needed.)

If I decide to use MSYS environment generally, those directories are
added to system PATH setting and emacs implicitly refers to the value.
In such case, I will call gdb without directory prefix.
But currently it is problematic and I am likely to search for another
gdb binary.
