Because of this, it is necessary to modify unexec.c slightly. ----------------------------- unexec.c diffs ----------------------------- *** /usr/src/local/bin/gnumacs/dist/src/unexec.c.orig Thu Feb 11 19:52:58 1988 --- /usr/src/local/bin/gnumacs/dist/src/unexec.c Thu Mar 31 15:50:13 1988 *************** *** 304,310 **** --- 304,314 ---- static MAGIC NEWMAGIC = {MY_ID, DEMAND_MAGIC}; #define N_TXTOFF(x) TEXT_OFFSET(x) #define N_SYMOFF(x) LESYM_OFFSET(x) + #ifdef EXEC_STRUCT + static struct EXEC_STRUCT hdr, ohdr; + #else static struct exec hdr, ohdr; + #endif /* no EXEC_STRUCT */ #else /* not HPUX */ *************** *** 323,329 **** --- 327,337 ---- ((x).fmagic)!=FMAGIC && ((x).fmagic)!=IMAGIC) #define NEWMAGIC FMAGIC #else /* IRIS or not USG */ + #ifdef EXEC_STRUCT + static struct EXEC_STRUCT hdr, ohdr; + #else static struct exec hdr, ohdr; + #endif /* no EXEC_STRUCT */ #define NEWMAGIC ZMAGIC #endif /* IRIS or not USG */ #endif /* not HPUX */ *************** *** 963,969 **** struct scnhdr bss_section; }; ! #ifdef IRIS_4D #define DEFAULT_ENTRY_ADDRESS start #else #define DEFAULT_ENTRY_ADDRESS __start --- 971,977 ---- struct scnhdr bss_section; }; ! #ifdef IRIS_4D || tek4300 #define DEFAULT_ENTRY_ADDRESS start #else #define DEFAULT_ENTRY_ADDRESS __start ----------------------------- m-tek4300.h ----------------------------- /* m- file for tek4300.
