-fpermissive required to build guitarix

[slyrus]

with the latest source I have to do the following to get guitarix to build:

CPPFLAGS=-fpermissive ./waf distclean configure

otherwise I get the following error:

../src/headers/gx_system.h: In instantiation of ‘bool gx_system::atomic_compare_and_exchange(T**, T*, T*) [with T = _jack_session_event]’:
../src/gx_head/engine/gx_jack.cpp:1110:79:   required from here

Same as #63

Indeed. My bad. Will close.
