Hi.

I took following error messages when building process has reached at 97%.

c:/oce/oce/src/ViewerTest/ViewerTest_ViewerCommands.cxx:248:37: error: invalid c
onversion from 'LRESULT (__attribute__((__stdcall__)) *)(HWND, UINT, WPARAM, LPARAM) {aka long int (__attribute__((__stdcall__)) *)(HWND__*, unsigned int, unsig
ned int, long int)}' to 'Standard_Address {aka void*}' [-fpermissive]
       ::LoadCursor (NULL, IDC_ARROW));
                                     ^

I use Windows7 32bit and MinGW4.8 + msys1.0.

Does anyone know how to fix this ?

I fixed it by my own.

I use cast from `LRESULT` to `Standard_Address` .

mingw 5.3 is quite old, though I'm unable finding exact information about this release.
Have you tried up-to-date version of Mingw-w64?
