Please don't write it that way.  If we ever decide that
AC_LIBTOOL_DLOPEN should expand to shell code (and not just change some
state at M4 time, which then induces a shell snippet elsewhere), then
the above could silently fail, while mine wouldn't.  You could write
  AS_IF([test "${enable_static_modules}" = "no"], [:; AC_LIBTOOL_DLOPEN])

Cheers,
