I carefully didn't rebuilt anything after the failure in i686-pc-cygwin/libgcc like before and cc1 seems to work, BUT xgcc still does not work (with the same symptoms). xgcc --version (or -dumpspecs) shows something on stdout, but when piped into wc, there is no output... Strange. The __DTOR_LIST__ contains a single item: deregister_frame_dtor (see attachment 32602). Also the specs file is not built (is built empty, see in attachment the -dumpspecs parameter), this is probably the cause of the "xgcc: error: unrecognized command line option 'X'" (with X=--version, or -mtune=generic, or -march=pentiumpro) when the -B/tmp/lcl/tmp/gcc/obj/gcc/ option is used.
