# We check two things: where the include file is for hash_map, and
|
|
# what namespace hash_map lives in within that include file. We
|
|
# include AC_TRY_COMPILE for all the combinations we've seen in the
|
|
# wild. We define one of HAVE_HASH_MAP or HAVE_EXT_HASH_MAP depending
|
|
# on location, and HASH_NAMESPACE to be the namespace hash_map is
|
|
# defined in.
|
|
#
|
|
# Ideally we'd use AC_CACHE_CHECK, but that only lets us store one value
|
|
# at a time, and we need to store two (filename and namespace).
|
|
# prints messages itself, so we have to do the message-printing ourselves
|
|
# via AC_MSG_CHECKING + AC_MSG_RESULT. (TODO(csilvers): can we cache?)
