 Hello GRASS developers,

 When trying to compile recent versions of GRASS (v.6 development branch or
 GRASS 7) I encountered an error during compilation of nviz related to the
 function 'strcasecmp' which seems to be included through several layers of
 the wxgtk libraries.  Please see the command line output below.

 ----

 I am not experienced enough of a programmer to know the "right" way to
 solve this problem, but I was able to make a workaround by modifying the
 file grass6_devel/gui/wxpython/nviz/grass6_wxnviz.i to include the
 statement #include <strings.h>

 The first lines of grass6_wxnviz.i in my patched version (which does
 compile)  look like this:

 {{{
 /* File: nviz.i */

 %module grass6_wxnviz
 %{
 #include <strings.h>
 #include "nviz.h"
 #include <grass/gsurf.h>
 #include <grass/gstypes.h>
 #undef check
 %}
 }}}
 etc...
