[U-Boot-Users] STD_C and STDC_

Wed Dec 13 04:02:15 CET 2006

Hello!
   Everyone,I was reading the U-boot of the mpc8260 in recent months. And I was a freshman. Yesterday,When I was reading the U-boot1.1.4\include\malloc.h, I was puzzled by the ln223 and the ln224 (#ifndef _STD_C  #ifdef  _STDC_).
I don't understand the differeces between the  "_STD_C" and "_STDC_".Could anyone can help me?
  Thank you very much!

                                                                py
