           Summary: KDevelop does know the "template < typename = >"
                    construct
           Product: kdevelop
           Version: 4.2.2
          Platform: Debian testing
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: cpp-parser
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: cberger@cberger.net


Version:           4.2.2 (using KDE 4.6.5) 
OS:                Linux

Apparently, in template definition, typename does not have to be followed by an
identifier.

The following construct is legal c++:

template < typename = int >

In reality it is mostly useful to do the following

template < typename = std::enable_if< SomeTest >::type >
void foo()
{
}

And depending on the result of SomeTest the function is generated or not. Well
anyway, if you input the above function (or similar) in kdevelop, kdevelop
underlight in red the "=" (and the template keyword too). While it should not.




Reproducible: Always

Steps to Reproduce:
To reproduce, in a cpp file, paste the following:


#include <utility>

template < typename = std::enable_if< false >::type >
void foo()
{
}

int main(int argc, char** argv)
{

  foo();
}


Actual Results:  
the equal in "typename =", the template keyword and the last ">" are wrongly
underlight in red.

Expected Results:  
Nothing is underlighted.
