[BUG]: Cannot parse Enum in unnamed namespace

[sogoogos]

Problem description

I have something like:

#include <iostream>

namespace
{
    enum MyEnum
    {
        A,B
    };
}

int main(){
        std::cout << "hello" << std::endl;
}

Then got:

In [8]: header = CppHeaderParser.CppHeader("main.cpp")

   3428 self.stack = []

   3592 if tok.value != "enum":
-> 3593     raise self._parse_error((tok,), "enum")
   3595 location = tok.location

CppParseError: unexpected 'namespace', expected 'enum'

The above exception was the direct cause of the following exception:
