# if you add an AC_DEFINE() for a symbol that appears in an exported

# external modules like those in examples can use pkg-config to get the
# same symbols Snort did. See PERF_PROFILING for an example.
#
# those should be going to AM_CPPFLAGS but adding the include paths breaks
# with both += and x='$x ...' forms.
