There are three machine types for different versions of 36 SunOS. All are derived from Berkeley 4.2, meaning that you should 37 use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will 38 need to use sun3 on Sun 2's running SunOS release 3. 39 40 For SunOS release 4 on a Sun 3, use -machine=sun3 and 41 -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve 42 problems caused by bugs in the "export" version of SunOS 4. 43NOTE-END */ 44 45/* Define WORDS_BIG_ENDIAN iff lowest-numbered byte in a word 46 is the most significant byte. */ 47 48#define WORDS_BIG_ENDIAN 49 50/* Say this machine is a 68000 */ 51 52#ifndef m68000 53#define m68000 54#endif 55 56/* Use type int rather than a union, to represent Lisp_Object */ 57 58#define NO_UNION_TYPE 59 60/* Sun can't write competent compilers */ 61#define COMPILER_REGISTER_BUG 62 63/* XINT must explicitly sign-extend */ 64 65#define EXPLICIT_SIGN_EXTEND 66 67/* Data type of load average, as read out of kmem. */ 68 69#define LOAD_AVE_TYPE long 70 71/* Convert that into an integer that is 100 for a load average of 1.0 */ 72 73#define LOAD_AVE_CVT(x) (int) (((double) (x)) * 100.0 / FSCALE) 74 75/* Say that this is a Sun 2; must check for and maybe reinitialize 76 the "sky" board. */ 77 78#define sun2 79 80/* Must use the system's termcap.
