#
# SYNOPSIS
#
#   AX_BERKELEY_DB_CXX([MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
#   This macro tries to find Berkeley DB C++ support. It honors
#   MINIMUM-VERSION if given.
#
#   If libdb_cxx is found, DB_CXX_HEADER and DB_CXX_LIBS variables are set
#   and ACTION-IF-FOUND shell code is executed if specified. DB_CXX_HEADER
#   is set to location of db.h header in quotes (e.g. "db3/db_cxx.h") and
#   AC_DEFINE_UNQUOTED is called on it, so that you can type
#
#     #include DB_CXX_HEADER
#
#   in your C/C++ code. DB_CXX_LIBS is set to linker flags needed to link
#   against the library (e.g. -ldb3.1_cxx) and AC_SUBST is called on it.
#
#   when specified user-selected spot (via --with-libdb) also sets
#
#     DB_CXX_CPPFLAGS to the include directives required
#     DB_CXX_LDFLAGS to the -L flags required
