+dnl SGI mipsPro compiler gives this warning for "conversion from pointer to
+dnl same-sized integral type" even when there is an explicit cast and as there
+dnl is no way to turn it off and there are hundreds of these warnings in wx
+dnl sources, just turn it off for now
+dnl
+dnl a better long term solution would be to use #pragma set/reset woff in
+dnl wxPtrToUInt() and use it instead of casts elsewhere
