[cfp-interest 3829] Annex H.13#4

[Damian McGuckin]

 	Use of the macros carg, cimag, conj, cproj, or creal with any
 	argument of standard floating type, binary floating type, or
 	complex type invokes a complex function. Use of the macro with an
 	argument of a decimal floating type results in undefined behavior

Why does the C standard mandate a function be called? It seems overly
restrictive.

Also, I would prefer the second sentence say

 	The use of a macro with a decimal floating type argument is
 	undefined behavior,
OR
 	The use of a macro with an argument of decimal floating type is
 	undefined behavior,

because the currently might be confused with the concept of "decimal floating
type result".
