Known bug. (at least, I found it and I mailed debian-sparc and
Miguel de Icaza, without any answer yet).
I think it fails only with `strcmp', and only if one of the
two arguments is a string constant. Can anyone confirm that? I
haven't tested all the functions, but the rest of the file
/usr/include/bits/string2.h (where that macro is defined) seems OK.
I've just mailed Ulrich Drepper... waiting for his answer :)
BTW: I'm building a new glibc now, which will fix the
getdomainname() bug (ie, "Unimplemented SPARC system call 162"), and
some other things... I'll see if I can fix that too.
