It seems that Qt include files can mess the compiler ! I mean including header
files for Qt components causes errors in code that normally compiles well. See
this example :

------------------------------------------------------------------------------------------


Everything's ok, the make script contonues. But when I had the header
for Qt in
the file :

------------------------------------------------------------------------------------------
#include <qapplication.h>
#include <qscrollview.h>
#include <qlabel.h>
#include <qvbox.h>
#include <qlistview.h>
#include <qtable.h>
------------------------------------------------------------------------------------------

I get the following output :

------------------------------------------------------------------------------------------

               from elisa_reduction.h:37,
               from elisa_box_reduction.h:27,
               from elisa_box_reduction.cpp:14:

Thus let me apologize, the problem does not come from the libsig
library... but
from Qt !!?
