As suggested in some other posting, you have compiled fvwm without
shape support

  $ ./configure --disable-shape

Thus, fvwm does not do anything abot shaped window which is also
the reason why you need

> Style "oclock" BorderWidth 0,StaysOnTop
                 ^^^^^^^^^^^^^

Otherwise, a border would be drawn. Since fvwm doe not use shape
masks, the transparent background of the window is never drawn.
Try to move the oclock window: there is no transparency, the
backgorund just moves with the window. To make it work, don't
use --disable-shape.

Bye
