Hi Olivier,
Thanks very much for the quick fix/response. I've tried the revision 24389 and
both modules (vlc and vlcinternal) compiles fine. =)
The only thing I really have to do is modifiy the
include/vlc/mediacontrol_structures.h file, in order to change uint32_t to
u_int32_t. It seems that gcc would complain about some syntax errors with
uint32_t but it would compile ok with u_int32_t. Notice that this only seems
to affect the vlc extension and not the vlcinternal module!
