# 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
# freedom.
