cast errors reported by a OsX cmake build

[Dirk Jagdmann <doj () cubic org>]

I just tried to use cmake to build current Wireshark SVN trunk source 
code. It fails early on with errors like:


[  5%] Building C object tools/lemon/CMakeFiles/lemon.dir/lemon.c.o
/Users/djagdmann/ws-trunk/trunk/tools/lemon/lemon.c:443:8: error: cast 
from 'char *' to 'struct action *' increases required
      alignment from 1 to 8 [-Werror,-Wcast-align]
  ap = (struct action *)msort((char *)ap,(char **)&ap->next,
       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/Users/djagdmann/ws-trunk/trunk/tools/lemon/lemon.c:457:24: error: cast 
from 'char *' to 'struct state *' increases required
      alignment from 1 to 8 [-Werror,-Wcast-align]
    newaction->x.stp = (struct state *)arg;

and many more of this type. Is somebody looking into cmake builds on OsX?
