CParser doesn't work with comments

[denismazzucato]

CParser doesn't seem to work well with comments:

from pycparser.c_parser import CParser

ast = CParser().parse(r'''
int main() {
  // comment
}
''')

raises "ParseError: :3:3: before: /"

In fact, one needs to activate cpp parsing with flag "-E" to obtain the ast of such code, the following works:

from pycparser import parse_file
ast = parse_file('examples/example.c', use_cpp=True, cpp_path='gcc', cpp_args=r'-E')
