error: call of overloaded ‘abs(double&)’ is ambiguous

I got this when building:

/home/liu/source/Agui/src/Agui/Gui.cpp: In member function ‘void agui::Gui::processInertia()’:
/home/liu/source/Agui/src/Agui/Gui.cpp:1931:32: error: call of overloaded ‘abs(double&)’ is ambiguous

I fixed this by changing all ads(double) to fabs, but I think I should report this issue any way.

Could you submit a PR?

I'm sorry I do not have the commit any more, i just find out where the abs(double) used and change them to fabs(double)
