Subject: [PATCH] configure.ac: detect readline via pkg-config when possible
pkg-config automatically handles static linking situations, where for
example readline is linked against ncurses, and therefore -lncurses
needs to be passed in addition to -lreadline.
This proposal uses pkg-config when available. If pkg-config is not
found, or readline is not found via pkg-config, we fallback to the
existing AC_CHECK_LIB(). This AC_CHECK_LIB() test is modified to set
READLINE_LIBS, like PKG_CHECK_MODULES() does. The Makefile.am
consequently uses READLINE_LIBS instead of hardcoding -lreadline.
