atof(), yes (and it's also part of POSIX).  But atoff() is not in C (not 
even in the C1x draft in document n1516).  The question here is about 
atoff().

Portable programs should not be using atoff().  However, cygwin is 
exporting it, and remoing atoff() _will_ break applications linked 
against cygwin1.dll.

You can remove the declarations from headers, so that new apps won't use 
it, but you may NOT remove the function itself, without breaking shared 
library clients of newlib like cygwin.
