K.B. Williams kindly agreed to work on adding to the DJGPP library
long double math functions mandated by C9x.  One of the specifications
of the standard says that the `nan' function accepts a text string
which can modify the result to some extent.  But the standard is
silent about the details, saying that the effect of that string is
``implementation-defined''.

I'm guessing that they allow to produce the different forms of NaN
(QNaN etc.), but it would be nice to know what do other
implementations do, and whether this is really the intent to begin
with.

So could people please tell what they know about this, and perhaps
look on other systems to see what they produce?

Please CC K.B., as he does not read the mailing list.

TIA
