To remedy this in such a way that the version -header is made at compiletime, I wrote this small program. It is fully -portable, so should work quite happily for any other platform that might need -it. - -msg3states.c -~~~~~~~~~~~~ -Needed getopt.c from the port folder, then compiled and worked fine. - - -tiff.h -~~~~~~ - -====1==== - -The symbol _MIPS_SZLONG, if not defined, causes a compiler error. Fixed by -ensuring it does exist. This looks to me like this wouldn't be an -Acorn-specific problem. The new code fragment is as follows: - -#ifndef _MIPS_SZLONG -#define _MIPS_SZLONG 32 -#endif -#if defined(__alpha) || _MIPS_SZLONG == 64 - - - -tiffcomp.h -~~~~~~~~~~ - -====1==== - -#if !defined(__MWERKS__) && !defined(THINK_C) -#include <sys/types.h> -#endif - -Acorn also doesn't have this header so: - -#if !defined(__MWERKS__) && !defined(THINK_C) && !defined(__acorn) -#include <sys/types.h> -#endif - -====2==== - -#ifdef VMS -#include <file.h> -#include <unixio.h> -#else -#include <fcntl.h> -#endif - -This seems to indicate that fcntl.h is included on all systems except -VMS. Odd, because I've never heard of it before. Sure it's in the ANSI -definition? Anyway, following change: - -#ifdef VMS -#include <file.h> -#include <unixio.h> -#else -#ifndef __acorn -#include <fcntl.h> -#endif -#endif - -This will probably change when I find out what it wants from fcntl.h! - -====3==== - -#if defined(__MWERKS__) || defined(THINK_C) || defined(applec) -#include <stdlib.h> -#define BSDTYPES -#endif - -Added RISC OS to above thus: - -#if defined(__MWERKS__) || defined(THINK_C) || defined(applec) || defined(__acorn) -#include <stdlib.h> -#define BSDTYPES -#endif - -====4==== - -/* - * The library uses the ANSI C/POSIX SEEK_* - * definitions that should be defined in unistd.h - * (except on VMS where they are in stdio.h and - * there is no unistd.h). - */ -#ifndef SEEK_SET -#if !defined(VMS) && !defined (applec) && !defined(THINK_C) && !defined(__MWERKS__) -#include <unistd.h> -#endif - -RISC OS is like VMS and Mac in this regard.

Will -leave it on for the time being and see if it works! (Likely if -everything else does.) - -... Seems to be OK ... - -====7==== - -Added to the end: - -/* - * osfcn.h is part of C++Lib on Acorn C/C++, and as such can't be used - * on C alone.
