Script autoloading

Hi there, 

I have a project that makes use of a shared library, say librun.so. 
That library is part of the project and there's extensive python
script to support debugging. 

This python script is named librun.so-gdb.py so and is located
along librun.so. Thi way. GDB loads automatically.
Works perfect, no extra setup (other autoload-safe path). 

However, I struggle to make this working also on Windows, where the 
library is named "librun.dll", not "librun.so'. 

I thought I'd use .debug_gdb_scripts section as described in 
GDB manual, but this does not work very good since $cdir is 
not searched in that case. 

Any idea how to make it working on both, Linux and Windows with
no additional setup (other than autoload-safe path)? What's is the 
rationale for excluding $cdir from source directories when searching
for scipts?

Thanks.

Best, Jan
