- Fix missing prototypes
- Fix some 64-bit related problems (XtVaGetValues)
- Fix crash on dtcreate startup in create_applicationShell1()
- Add XmeFlushIconFileCache() prototype from <Xm/IconFileP.h>
GetBaseName causes segfaults, because when the pathname
ends in a "/" it returns NULL. This happens when trying
to give a valid filename to dtcreate for an icon.
