[ *] The rcmd() functions (more concrete: the handling of .rhosts) does
not support netgroups and wildcards (+).
[ *] The first alias definition in locale.alias is ignored.
[PR libc/205]
[ *] When assembling a locale definition, that uses the "copy"
directive, with localedef, not only the copied category is
checked for errors, but the whole file containing the same
