# XXX - some versions of net-snmp-config, when run with --cflags,
# might set flags that won't work with cpp, and AC_CHECK_HEADERS
# might use cpp. To work around this, we just use --prefix to
# get the directory in which to search for header files, and
# construct CPPFLAGS from that, although that might miss -D or
# -U flags you get from --cflags; the -I flag should be
# sufficient for AC_CHECK_HEADERS' purpose.
