gtags: failed to parse template

Dear all,

GNU global 6.5.4 has trouble with the following template specialisation snippet:

> template <typename T>
> struct Foo<typename std::enable_if<sizeof(T) <= 2* sizeof(size_t)>::type>
> {};

gtags: failed to parse template [+2 ./foo.cpp].

If I use "<" instead of "<=" it still fails, but it works if I use ">". It's 
probably not expecting operator< to appear inside a template.

Cheers,
Lorenz
