#  to reduce the number of places that need to be edited when something
#  common changes.  If you include this file you may provide:
#
#  VENDOR_CFLAGS       - vendor specific flags to pass to the compiler
#  DISABLE_SHARED_LIBS - set this to 1 to disable shared libraries
#  LOPT                - library optimisation flags
#  UOPT                - user optimisation flags
