Summary: PyRun_SimpleString won't parse \\x

Initial Comment:
I'm trying to use Python 2.4.2 from C on Win XP. 
The following line of C code generates an error:

test.c:
PyRun_SimpleString( "s = 'C:\\xyz'\n" );

Output:
ValueError: invalid \x escape


The error message only occurs if 'x' follows the 
slashes '\\x'. That is, no other letter causes this 
problem:

PyRun_SimpleString( "s = 'C:\\ayz'\n" );
PyRun_SimpleString( "s = 'C:\\yyz'\n" );

Using forward slashes also prevents the error:
PyRun_SimpleString( "s = "C:/xyz'\n" ); // ok

C uses the same escape rules as Python, so your first
test snippet looks like "C:\xyz" to Python.  which is
is an invalid string literal, just as the message says.

see the Python language reference to details on string
literal syntax.
