[gtkada] Font on Win32 cant load MS Sans Serif 8

[Mark Gawler]

I've written a small GtkAda Application, which works fine under Linux, but
moving to a Windows NT platform the application runs but continually
streams out:
"Couldn't load font "MS Sans Serif 8" falling back to Sans 8"

The same happens when I run the Gtktest application, so its not restricted
to my code.

Is there an easy way to fix this?

Thanks
