okay, we did some testing and the results are really astonishing:

conftest.s1 is created from conftest.subs (inside configure). *.s* are
chunks of .subs (90 lines) for broken/old sed(1)s. the offending command
line boils down to "sed 90q conftest.subs > conftest.s1" which is to
"head -90 conftest.subs > conftest.s1" (:-P).  when doing this, some
leading characters of conftest.subs disappear! this is an NFS bug since it
works on the local file system (make is still runnning). sniffing the net
we see that my NFS server transfers the file correctly to the client but
the bytes disappear in the client. strace(1)ing "sed" (broken) and
"cat" (works) on the same file we see: sed mmap()s the file, cat read()s
it. so mmap()ing over nfs is broken on my old redhat 6.1 sparc. mounting
the nfs "sync" or not-"sync" just changes the amount of bytes that get
lost... funny, isnt it...

Bye,
    Raimi

P.S.: i'll post the result of the local-fs build later this night (or
week, we'll see)
