* source/compiler/gencobj.c
    ! fixed to allow = for the C compiler options
    ( suggested by Przemyslaw Czerpak )
    ! added support of OpenWatcom C
    ! cleaned the verbose option
  * source/rdd/dbfcdx/dbfcdx1.h
    ! changed to allow OpenWatcom C build
    ( suggested by Przemyslaw Czerpak )
