# ----------------------
# func_stripname_cnf prefix suffix name
# strip PREFIX and SUFFIX off of NAME.
# PREFIX and SUFFIX must not contain globbing or regex special
# characters, hashes, percent signs, but SUFFIX may contain a leading
# dot (in which case that matches only a dot).
#
# This function is identical to the (non-XSI) version of func_stripname,
# except this one can be used by m4 code that may be executed by configure,
# rather than the libtool script.

dnl tag define a new lt_????_link_test_code variable,
dnl but it's only used here...
