The Autoconf or CVS bit bucket?  In any case, I thought this was the
subject of a different email thread and hadn't decided how to respond to
that yet.

It might be enough to say, "hey, configuring on this system fails
because the linker doesn't report errors correctly and Floss deals with
it like this!  Would you find this useful?"

Could you write a configure test that can determine that it is necessary
to define _XOPEN_SOURCE_EXTENDED?  It is possible that the alternative
is simply putting a note in INSTALL that it was necessary to supply this
option on Tandem.  I have a dim recollection of a discussion on
bug-gnulib about defining _XOPEN_SOURCE causing problems due to a
difference of interpretation between platforms.  I don't recall if the
bugs were gross or subtle.  Not sure what _XOPEN_SOURCE's relationship
to _XOPEN_SOURCE_EXTENDED is either.
