GTAGSLIBPATH definition search

[Pavel Nedev]

Hi,

Thank you for GTags, it's a great and very powerful tool!

I stumbled upon something recently, I do not know if this is a bug or just the 
expected behavior. Here is the scenario:

I make tags for my libraries includes (/usr/include). I set GTAGSLIBPATH to 
/usr/include.
I make tags for my project.
When I execute

global -dxMT FindReference

I get the definition of the 'FindReference' function (that's from my project) 
in the 'x' (ctags) format:

FindReference     541 src/GTags.cpp    void FindReference()

When I execute

global -dxMT resolve

I get the following results for Boost 'resolve' function (from /usr/include):

Warning: source file './boost/asio/detail/resolver_service.hpp' is not 
available.

This is not exactly in 'x' (ctags) format - the match line from the file is 
actually missing.
Is this expected or am I doing the search the wrong way?

Thank you!
