# Edit the variables to suit your system.
#
#   use -DAUDIT to enable some internal sanity checks
#   use -DMEM_CHECK to check the return value of malloc()
#      (superseded by AUDIT)
#   use -DMEM_DEBUG to enable memory leak research (warning: this
#      slows down ucpp a bit, and greatly increases memory consumption)
#   use -DINLINE=foobar to enable use of the 'foobar'
#      non standard qualifier, as an equivalent to the C99 'inline'
#      qualifier. See tune.h for details.
