YES! It's worked!
I use next:

export LANG=C
unset LC_ALL
export LC_CTYPE=ru_RU.KOI8-R

I use the conserver port for my terminal emulator and a terminal type of
"vt100".

Subject: (hopefully) working libc_r for sparc64

Content-Disposition: inline

Hi,

I think I got libc_r working, after rewriting longjmp() and friends so
that they do not require the corresponding setjmp() to be done in an
ancestor function in the call graph any more, i.e. it can be used to
switch stacks now. This might also get other threading packages to
work, e.g. ruby's integrated thread manager.

I've attached a diff that contains these changes, and also patches to
libc_r to add the necessary MD code. The latter are based on diffs
that des posted to this list some time ago.
To apply this, you will need to do a 'mkdir libc_r/arch/sparc64' in
your src directory before.

It would be nice if people could test these changes a bit, both with
applications that make extensive use of the *jmp() functions and with
libc_r-using programs. Please be aware however that by installing an
experimental libc you might hose your system (although things seem to
work fine for me).

- Thomas
