Xfce4-panel compiling problem

[Michal M. Lechanski]

Hi, I'm trying to compile a today's cvs version and have a problem to 
compile the panel:

xfcombo.c:308: conflicting types for 'create_completion_combo'
xfcombo.h:79: previous declaration of 'create_completion_combo'
make[2]: *** [xfce4_panel-xfcombo.o] Error 1

How to avoid this error?

TiA
