[issue5143] OS X: Py_SetProgramName argument has type char*; should be wchar_t*

[Mark Dickinson]

New submission from Mark Dickinson <dickinsm at gmail.com>:

When building the py3k branch on OS X, I get the following warning:

gcc -c -fno-strict-aliasing -g -Wall -Wstrict-prototypes  -I. -IInclude -
I./Include   -DPy_BUILD_CORE -o Modules/main.o Modules/main.c
Modules/main.c: In function ‘Py_Main’:
Modules/main.c:491: warning: passing argument 1 of ‘Py_SetProgramName’ 
from incompatible pointer type

This *looks* like it might be a genuine problem. Lines 490-493 of main.c 
(which occur inside an #ifdef __APPLE__) look like this:

if ((p = Py_GETENV("PYTHONEXECUTABLE")) && *p != '\0')
	Py_SetProgramName(p);
else
	Py_SetProgramName(argv[0]);

The return from Py_GETENV (which calls the system getenv) has type char*, 
but Py_SetProgramName expects something of type wchar_t*.

However, I don't know enough about this part of Python to tell for sure 
whether there's really something wrong here.

Ronald, any ideas?
