Committee Draft subsection: 7.7.11.2

Title: The nan() function seems pointless and confusing


Detailed description:

This implies that the NaN macro takes a string argument, which is
incompatible with its use in 7.7 Mathematics.  Given the statement in IEEE
754 that only one NaN of each type need be provided, and the absence of
facilities for handling different NaN values both in IEEE 754 and C9X, I
suggest scrapping this function entirely.
