dnl AS_LIBTOOL(PREFIX, CURRENT, REVISION, AGE, [RELEASE])

dnl example
dnl AS_LIBTOOL(GST, 2, 0, 0)

dnl this macro
dnl - defines [$PREFIX]_CURRENT, REVISION and AGE
dnl - defines [$PREFIX]_LIBVERSION
dnl - defines [$PREFIX]_LT_LDFLAGS to set versioning
dnl - AC_SUBST's them all

dnl if RELEASE is given, then add a -release option to the LDFLAGS
dnl with the given release version
dnl then use [$PREFIX]_LT_LDFLAGS in the relevant Makefile.am's

dnl call AM_PROG_LIBTOOL after this call

AC_DEFUN([AS_LIBTOOL],
[
  [$1]_CURRENT=[$2]
  [$1]_REVISION=[$3]
  [$1]_AGE=[$4]
  [$1]_LIBVERSION=[$2]:[$3]:[$4]
  AC_SUBST([$1]_CURRENT)
  AC_SUBST([$1]_REVISION)
  AC_SUBST([$1]_AGE)
  AC_SUBST([$1]_LIBVERSION)

  [$1]_LT_LDFLAGS="$[$1]_LT_LDFLAGS -version-info $[$1]_LIBVERSION"
  if test ! -z "[$5]"
  then
    [$1]_LT_LDFLAGS="$[$1]_LT_LDFLAGS -release [$5]"
  fi
  AC_SUBST([$1]_LT_LDFLAGS)

  AC_LIBTOOL_DLOPEN
