Would we?  My understanding is that code passed to PyRun_String()

confirm or deny?
I'm not sure of that. I suspect you'll need to pass CRs on windows.
If anyone manages to compile the following code on Windows...
#include "Python.h"
void
run_program(const char *program)
{
        PyObject *ret, *globals, *locals;
        printf("> running:\n%s\n", program);
        globals = PyDict_New();
        locals = PyDict_New();
        ret = PyRun_String(program, Py_file_input, globals, locals);
        if (ret) {
                Py_DECREF(ret);
                printf("\n");
        } else {
                PyErr_Print();
        }
        Py_DECREF(locals);
        Py_DECREF(globals);
        printf("> end\n\n");
}
int
main(int argc, char *argv[])
{
        const char *program1 = "print 1\nprint 2\n";
        const char *program2 = "print 1\r\nprint 2\r\n";
        Py_Initialize();
        printf("> Initialized.\n");
        printf("> Python %s\n", Py_GetVersion());
        run_program(program1);
        run_program(program2);
        Py_Finalize();
        printf("> Finalized.\n");
}
On my Fedora Core 2, I need to complile it with the following command:
gcc -I/usr/include/python2.3 -L/usr/lib/python2.3/config py-test.c -o py-test\
-lpython2.3 -ldl -lm -lpthread -lutil
This is my first attempt to embed python, so I may be missing something...
On Linux, you get:
$ ./py-test 2>&1 | cat -v
Initialized.
Python 2.3.3 (#1, May  7 2004, 10:31:40)
[GCC 3.3.3 20040412 (Red Hat Linux 3.3.3-7)]
running:
print 1
print 2
1
2
end

running:
print 1^M
print 2^M
  File "<string>", line 1
    print 1^M
           ^
SyntaxError: invalid syntax
end

Finalized.

I bet on windows the first program fails and the second is ok.
