Summary: last threads fixes broke linker

Initial Comment:
In current cvs, -pthread and -ieee is properly set for
OSF1/Tru64Unix. Unfortunately, -ieee is somewhat passed
to linker:

I see; -ieee is indeed passed to ld. I am a programmer, but
I cannot develop on Tru64. So we have to wait until a
programmer with access to Tru64 shows up.

Actually, I don't know why -ieee is needed, I'm not a
programmer, sorry. The manpage cc(1) says:

  -ieee
      Ensure support of all portable features of the IEEE
Standard for Binary
      Floating-Point Arithmetic (ANSI/IEEE Std 754-1985),
including the
      treatment of denormalized numbers, NaNs, and
infinities and the han-
      dling of error cases. This option also sets the
_IEEE_FP C preprocessor
      macro.

      If your program must use IEEE signaling features that
are not portable
      across different IEEE implementations, see the ieee(3)
reference page
      for a discussion of how to access them under the Tru64
UNIX operating
      system.



Yes, -ieee is not listed in mapage for ld(1). I do not have
an access to that machine probably for a whole week, but are
you sure the -ieee is not in teh generated Makefiles passed
inside some variable to linker directly?

Is it not the case that cc(1) supports -ieee? If so, why
does it then pass the option to ld?

Perhaps it depends on the cc version whether -ieee is
supported? Perhaps the compiler should be invoked with a
different name?

Please don't make us guess as to how your operating system
works. If you can contribute to a solution, that would be
much appreciated.
