>Description:
        g_convert fails when trying to convert to or from WCHAR_T on NetBSD
        because of limitations in the system iconv implementation. glibmm
        uses this in its ustring class implementation, so any application
        using glibmm will fail.
>How-To-Repeat:
        Build the following application on NetBSD:

        $ cc glibconvert.c -o glibconvert `pkg-config --cflags --libs glib-2.0`
        $ ./glibconvert

        ** (process:5615): WARNING **: g_convert failed: Conversion from 
character set 'UTF-8' to 'WCHAR_T' is not supported

        The same application works fine on Linux:

        $ ./glibconvert 
        ** Message: g_convert success

/* g_convert test application */
#include <glib.h>

int
main(void)
{
        GError *gerror = NULL;
        gsize read, written;
        gchar *convstr;

        convstr = g_convert("hello", 5,
                            "WCHAR_T", "UTF-8", &read, &written,
                            &gerror);
        if (convstr == NULL)
                g_warning("g_convert failed: %s\n", gerror->message);
        else
                g_message("g_convert success\n");
        return 0;
}
