What has changed is that unamed struct/unions are now not supported in ISO C mode (-ansi (r -std=c89 switch is given). Apparently there are two levels of support for these extenions. With -std=gnu89 (default). the GNU extemsions supported in prior gcc is still supported. With -fms-extensions, some additional MS extensions are also supported. Regardless of the commandline switch. I think you can still mark structs/unions with __extension__ to get the std-gnu89 anon support for a specific declaration. I can't find where this is documented. These are testsuite cases (in source distro) that give examples gcc.dg/anon-struct-1.c gcc.dg/anon-struct-2.c gcc.dg/anon-struct-3.c gcc.dg/20011008-1.c gcc.dg/20020527-1.c Plus more in C++ dirs Danny > >Sergey > http://search.yahoo.com.au - Yahoo!
