 I just got to thinking about the warning messages that gcc 4.5.3 emits
 on netbsd-6.  It said "built-in function ceill()".
 
 I take it to mean that the compiler is inserting some mysterious internal
 implementation of ceill() and simply grousing about the implicit
 declaration (due to missing prototype) not matching that of its mysterious
 internal implementation.
 
 So, the prototype in -current <math.h> silences that complaint, but
 still leaves the compiler inserting its own code for ceill().
 
 It would also appear that this is present in the x86-family-target
 compilers, but not in powerpc-target compiler (others?)?
