makeinfo-compilation-sentinel should check if frame is special

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have     
  (setq  special-display-regexps
           '("Help" "ChangeLog*" "\\*compilation\\*" "\\*grep\\*" )))

If I do a makeinfo-buffer on completion it attempts to switch the special
frame buffer holding the compile buffer to the generated info which causes an 
error

error in process sentinel: Cannot switch buffers in a dedicated window

It needs to check that it isn't a special buffer first...
