Description
I have built Typefaster: http://sourceforge.net/projects/typefaster/ which uses QT3 and not QT4. I was getting SIGFPE errors until I recalled floating point issues such as was seen in Cairo. I then happened on the fix in QT4: http://svn.netlabs.org/qt4/changeset/430 I was able to take the API_FPU_CW_Wrappers.h and update qt_os2.h: Index: qt_os2.h =================================================================== --- qt_os2.h (revision 188) +++ qt_os2.h (working copy) @@ -44,6 +44,9 @@

There is an update to QT4 that I am looking to bring over before closing this out.
Andy, as we are not updating qt3 at all feel free to include your changes to this official tree. or just provide a custom qt3. if you need svn write access let me know.
