Exuberant Ctags

Paste the following into a c++ header file
--------------------------
MY_MACRO(qwerty < 1);

class Abra : public Kadabra
{
};
-------------------------
Then say:
ctags --fields=+naimKzsS c++_header.h

Look at the output file - tags. The expected line:

Abra c++_header.h /^class Abra : public
Kadabra$/;" kind:class line:4 inherits:Kadabra

is missing! The offender seems to be the "<" in the
macro. Removing it or even just changing it to ">"
seems to fix the problem.
