-# ------------------------------------------------------

-# Use a cache variable name containing both the library and function name,

-# may have different results.
-#
-# Note that using directly AS_VAR_PUSHDEF([ac_Lib], [ac_cv_lib_$1_$3])
-# is asking for trouble, since AC_CHECK_LIB($lib, fun) would give
-# ac_cv_lib_$lib_fun, which is definitely not what was meant. Hence
-# the AS_LITERAL_IF indirection.
-#
-# FIXME: This macro is extremely suspicious. It DEFINEs unconditionally,
-# whatever the FUNCTION, in addition to not being a *S macro. Note
-# that the cache does depend upon the function we are looking for.
-#
-# It is on purpose we used `ac_check_lib_ext_save_LIBS' and not just
-# `ac_save_LIBS': there are many macros which don't want to see `LIBS'
-# changed but still want to use AC_CHECK_LIB_EXT, so they save `LIBS'.
-# And ``ac_save_LIBS' is too tempting a name, so let's leave them some
