  DESCRIPTION
!        The tolower() function has as a domain a type int, the value of which
         is representable as an unsigned char or the value of EOF. If the
         argument has any other value, the argument is returned unchanged. If
         the argument of tolower() represents an upper-case letter, and there
         exists a corresponding lower-case letter (as defined by character type
         information in the locale category LC_CTYPE),  the result is the

--- 25,39 ----
  
         The function tolower_l() behaves identically to tolower(), except
         instead of operating in the current locale, it operates in the locale
         specified by loc.
  
+        A macro form, _tolower() exists. It is defined for standards
+        conformance, particularly with legacy standards. It was deprecated in
+        POSIX 2008 (Issue 7), and its use is discouraged. The macro, on this
+        system, is just an alias for tolower().
+ 
  RETURN VALUES
         On successful completion, tolower() returns the lower-case letter
         corresponding to the argument passed. Otherwise, it returns the
         argument unchanged.
