To: djgpp AT sun DOT soe DOT clarkson DOT edu

Hi all,

This is probably a FAQ but I've noticed patches being distributed
in a certain format. Example illustrated below:


*** old/cdefs.h	Sat Mar 14 20:08:38 1992
--- cdefs.h	Sat Sep 17 23:44:46 1994
***************
*** 1 ****
--- 1,14 ----
+ #undef __P
+ #if defined(__STDC__) || defined(__cplusplus)
  #define __P(x) x
+ #else
+ #define __P(x)
+ #endif
+ 
+ #if defined(__cplusplus)
+ #define __BEGIN_DECLS	extern "C" {
+ #define __END_DECLS	};
+ #else
+ #define __BEGIN_DECLS
+ #define __END_DECLS
+ #endif


How are these sorts of files applied, and how are they created?
Any suggestions or documentation would be appreciated.



Regards, Ron.
