I have modified all the makefile.am and configure.ac of my project.

- For shared libraries, with -module libtool parameter, I Have this type 
of warning (error I presume):

libtool: link: warning: undefined symbols not allowed in i386-pc-mingw32 
shared libraries



- For executable, I have this type of error:

- For the shared libraries without -module option, all seem to be ok:

Can you help me ?
