I thought that UltraSparc is more 64-bit than it is :-)

That's bad. MC is not really good in handling error conditions like that.
Sometimes this message gets very annoying if things go wrong on VFS.

It is not realistic to expect every stat() to succeed, no matter what we
do with VFS. There are race conditions, there are cases like yours, there
may be NFS problems etc. Perhaps a better solution would be to have a flag
"stat_failed" in "struct file_entry", declared in dir.h, and mark such
files like staled links.

On the other hand, it should be possible to activate large file support in
MC using the standard Autoconf macro AC_SYS_LARGEFILE (only Autoconf 2.50
and above).

Unfortunately, simply adding AC_SYS_LARGEFILE to configure.in doesn't work
(RedHat Linux 7.1, i686) - I'm getting the same error "File XXX exists but
can not be stat-ed"

I'll try to fix it - if it works for me I'll make a snapshot for testing.
I'm still not sure if largefile support is good for everybody. Maybe I'll
fix AC_SYS_LARGEFILE so that it can be off by default.
