Macro line continuation bug #63

Closed dslijepcevic closed 3 years ago

dslijepcevic commented 3 years ago

test.c:

#define x\
 \

#include "test.h"

test.h:

int f();

Running pcpp --line-directive= --passthru-defines test.c produces the following output:

#define x int f();

If I omit the leading space on the second line of #define x then I get:

Traceback (most recent call last):
  File "/home/dux/.local/lib/python2.7/site-packages/pcpp/pcmd.py", line 140, in __init__
