[Kelly Hickel] I fully understand and support the fact that this doesn't
have to be in the autoconf, I have no problem with telling people they
have to get Floss and then do the CC above.  The problem is that this
still generates a broken cvs, in that it can't handle files over 52k.
The patch that I'm proposing to submit only deals with the 52k issue,
not fixing autoconf. I have previously submitted patches for detecting
the NSK/OSS environment, I do not believe they've been accepted, but
they haven't been bounced either.  They've vanished into the bit bucket.
Not encouraging.

[Kelly Hickel] I suspect that getting a fully functioning AutoConf on
NSK/OSS is beyond my time availability right now, even if I could
interest them in it.

[Kelly Hickel] As far as the _XOPEN_SOURCE_EXTENDED stuff goes, my quick
googling shows that it's present on several systems (including hpux,
z-os, tru-64).  On the NSK it was needed to resolve some socket calls.
It may be needed for other things, but it was definitely needed for
that.
