There are three machine types for different versions of 34 SunOS. All are derived from Berkeley 4.2, meaning that you should 35 use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will 36 need to use sun3 on Sun 2's running SunOS release 3. 37 38 For SunOS release 4 on a Sun 3, use -machine=sun3 and 39 -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve 40 problems caused by bugs in the "export" version of SunOS 4. 41NOTE-END */ 42 43/* Define WORDS_BIG_ENDIAN iff lowest-numbered byte in a word 44 is the most significant byte. */ 45 46#define WORDS_BIG_ENDIAN 47 48/* Say this machine is a 68000 */ 49 50#define m68000 51 52/* Use type int rather than a union, to represent Lisp_Object */ 53 54#define NO_UNION_TYPE 55 56/* Sun can't write competent compilers */ 57#define COMPILER_REGISTER_BUG 58 59/* XINT must explicitly sign-extend */ 60 61#define EXPLICIT_SIGN_EXTEND 62 63/* Data type of load average, as read out of kmem. */ 64 65#define LOAD_AVE_TYPE long 66 67/* Convert that into an integer that is 100 for a load average of 1.0 */ 68 69#define LOAD_AVE_CVT(x) (int) (((double) (x)) * 100.0 / FSCALE) 70 71/* Must use the system's termcap.
