PyUnicode_AsWideChar() result is signed, whereas it was stored in a unsigned
variable, and then the test was "n >= 0" which is always true to an unsigned
number. Patch written by Hallvard B Furuseth.
Instead of casting it to wchar_t* without conversion. It fixes a bug if Python
is compiled a non-ascii directory, different than the source code directory,
with C locale.
* _Py_fopen() and _Py_stat() come from Python/import.c
* (_Py)_wrealpath() comes from Python/sysmodule.c
* _Py_char2wchar(), _Py_wchar2char() and _Py_wfopen() come from Modules/main.c
* (_Py)_wstat(), (_Py)_wgetcwd(), _Py_wreadlink() come from Modules/getpath.c
on OSX. This fixes a small issue that was exposed
by running test_subprocess through regrtest (and
hence in a subdirectory).
Without this patch running python.exe from the
build tree will fail when these tree conditions
are true:
1) the CWD is not the root of build tree
2) python.exe is found through $PATH
3) the framework is not yet installed

Issue #7774: Set sys.executable to an empty string if argv[0] has been
set to an non existent program name and Python is unable to retrieve the real
program name.
Fix also sysconfig: if sys.executable is an empty string, use the current
working directory.

Fix test_executable introduce in previous commit (r78835): Windows is able to
retrieve the absolute Python path even if argv[0] has been set to a non
existent program name.

Another fix to test_executable() of test_sys: set the current working to avoid
the #7774 bug.
