# Determine shared object suffixes.
#
# Our method is to use the libtool variable $library_names_spec,
# set by using AC_PROG_LIBTOOL. This variable is a snippet of shell
# defined in terms of $versuffix, $release, $libname, $module and $jnimodule.
# We want to eval it and grab the suffix used for shared objects.
# By setting $module and $jnimodule to yes/no, we obtain the suffixes
# used to create dlloadable, or java loadable modules.
# On many (*nix) systems, these all evaluate to .so, but there
# are some notable exceptions.
# This macro is used internally to discover the suffix for the current
# settings of $module and $jnimodule. The result is stored in $_SOSUFFIX.
