I've been using -fnative-struct for all of my cygwin DLL builds recently. Anecdotal evidence (from Earnie, maybe?) indicates that it causes a noticeable speedup but I haven't really noticed anything myself. >2) How important is fastcall calling convention to cygwin apps.

I think it is necessary if we want gcc to be a replacement for MSVC. Out of curiousity, how does fastcall differ from attribute ((regparm (n)))? Are there any other patches that need to be added to 3.1 to make it a good Windows compiler? I know that the mingw/cygwin gcc 2.95.3 has a lot of Mumit Khan additions. Are these patches either unneeded or unnecessary for 3.1? cgf
