Ping? FYI, the cygwin distribution recently (Jul 4) released an updated binutils package (2.19.51) for cygwin-1.7. This version supports the --identify and --identify-strict options -- so, at least on cygwin-1.7 we won't be using the func_cygming_dll_for_implib_fallback function. Now, with the redesign proposed by Ralf back in January and implemented (take 3? take 4? I forget), we ordinarily use NEITHER func_cygming_dll_for_implib_fallback nor dlltool --identify-strict because, in the ordinary case, we have a libtool .la file and use it to track implib<->dll. NOW, the only time either of these two methods is used, is when someone specifies explicitly an implib or DLL on the link command passed to libtool: libtool mode=link .... /my/path/foo.dll.a -lbar-3.dll BUT...it's still nice that the (faster, less kludgy) dlltool method can now be used on cygwin-1.7. (No, the standard toolchain from the mingw.org guys doesn't yet support --identify-strict, so it still uses the fallback). -- Chuck
