I have my /etc directory tree under CVS control, so there's a directory /etc/env.d/gcc/CVS. "gcc-config -l" ignores the directory, but if I run (e.g.) "gcc-config 11", I get the configuration that was #10 in the list, so it's off by one. (gcc-config 1 gives me the help message.) It would be nice if that part of gcc-config also ignored the CVS directory.
fixed in cvs
Work fine for me now.
