+## FIXME some of these dependencies are platform-specific.
+## Eg callproc.c only depends on w32.h for WINDOWSNT builds.
+## One way to fix this would be to replace w32.h (etc) by $(W32_H),

+## Since the w32 build does not even use this file, you might ask
+## why these dependencies are here at all...

+## nsgui.h: In fact, every .o file depends directly or indirectly on
+## dispextern.h and hence nsgui.h under NS.  But the ones that actually
+## use stuff there are more limited.
