The startup directory is not included in the module search path - neither
in your embedded version, nor in the standard interpreter (it's only
included when running in interactive mode).

If you really want the current directory in sys.path, use the getcwd
function to obtain it. But make sure this is what you want - the directory
containing the executable might be a better choice (at least more
Note that Python already provides lots of ways to add directories to
sys.path (the default search path (see site.py), per-user site directories
(see PEP370), .pth files, the PYTHONPATH and PYTHONHOME environment
variables, the Windows registry, other ways I forgot...) So I'd ask why do
you want to add a non-standard one.
In C code, you can alter the initial search path by setting
Py_SetProgramName and Py_SetPythonHome. And you may even completely
replace getpathp.c source file with your own.
