Multi-line macro fails about ctypeslib

[trolldbois]

Not really,
the clang preprocessor should be doing it, not ctypeslib.

Okay. Just to make sure I described my issue clearly, I am only encountering a problem when I use the -k m option to include macros in the ctypeslib output. I am passing in a .h file to define constants and structure typedefs. If I include a multi-line macro in the .h file containing part of a structure definition, I can use that macro within structure typedefs in the .h file, and ctypeslib will process the macro correctly as long as I do not use the -k m option (I am guessing this is because the clang preprocessor is handling the macros in this case). If I use the -k m option I get the following error:

$ python3 "ctypeslib\clang2py.py" -c -k cdefmstu -o message_defs.py message_defs.h

KeyError: 'msg_type'

Here is the example message_defs.h file that causes this error:

#define MT_REQUEST_TEST_DATA 101
#define MT_TEST_DATA 102

#define RTMA_MSG_HEADER_FIELDS \
	int	msg_type; \
	int	msg_count; \
	double	send_time; \
	double	recv_time

typedef struct 
{ 
    RTMA_MSG_HEADER_FIELDS;
    int a; 
    int b; 
    double x; 
} MDF_TEST_DATA;

I had been assuming the issue was related to reading in one line at a time, but I tried redefining the macro on a single line like this, and got the same error: #define RTMA_MSG_HEADER_FIELDS int msg_type; int msg_count; double send_time; double recv_time

Does the -k m option rely on the clang preprocessor in the same way as when -k m is not specified?
Thanks.
