Это с какой это стати стандартные библиотеки обходятся без этого??? Вот пример заголовочного файла библиотеки stdio от компилятора Hi-Tech для PIC18: #ifndef _STDIO_H_ #define _STDIO_H_ #if z80 #define BUFSIZ 512 #define _NFILE 8 #else /* z80 */ #define BUFSIZ 1024 #define _NFILE 20 #endif /* z80 */ #ifndef _STDDEF typedef int ptrdiff_t; /* result type of pointer difference */ typedef unsigned size_t; /* type yielded by sizeof */ typedef unsigned short wchar_t; /* wide char type */ #define _STDDEF #define offsetof(ty, mem) ((int)&(((ty *)0)->mem)) #endif /* _STDDEF */ #ifndef _STDARG #include <stdarg.h> #endif #ifndef NULL #define NULL (0) #endif /* NULL */ extern int errno; /* system error number */ #ifndef FILE #if _HOSTED extern struct _iobuf { char * _ptr; int _cnt; char * _base; unsigned short _flag; short _file; size_t _size; } _iob[_NFILE]; #define FILE struct _iobuf #define L_tmpnam 81 /* max length of temporary names */ #define _MAXTFILE 8 /* max number of temporary files */ #if DOS #define FILENAME_MAX 81 /* max length of a pathname */ #define FOPEN_MAX 5 #endif extern struct _tfiles { char tname[L_tmpnam]; FILE * tfp; } * _tfilesptr; #else /* _HOSTED */ struct __prbuf { char * ptr; void (* func)(char); }; #endif /* _HOSTED */ #endif /* FILE */ #define _IOFBF 0 #define _IOREAD 01 #define _IOWRT 02 #define _IORW 03 #define _IONBF 04 #define _IOMYBUF 010 #define _IOEOF 020 #define _IOERR 040 #define _IOSTRG 0100 #define _IOBINARY 0200 #define _IOLBF 0400 #define _IODIRN 01000 /* true when file is in write mode */ #define _IOAPPEND 02000 /* file was opened in append mode */ #define _IOSEEKED 04000 /* a seek has occured since last write */ #define _IOTMPFILE 010000 /* this file is a temporary */ #define EOF (-1) #define _IOSTRING (-67) #define SEEK_SET 0 #define SEEK_CUR 1 #define SEEK_END 2 #define TMP_MAX 255 #if _HOSTED #define stdin (&_iob[0]) #define stdout (&_iob[1]) #define stderr (&_iob[2]) #ifdef DOS #define stdprn (&_iob[3]) #endif #define getchar() getc(stdin) #define putchar(x) putc(x,stdout) #else /* _HOSTED */ #include <conio.h> #define getchar() getche() #define putchar(x) putch(x) extern int cprintf(char *, ...); #pragma printf_check(cprintf) #if defined(_MPC_) && !defined(_PIC18) extern void _doprnt(char *, const register char *, ...); #else extern int _doprnt(struct __prbuf *, const register char *, register va_list); #endif /* _MPC_ */ #endif /* _HOSTED */ /* getc() and putc() must be functions for CP/M to allow the special * handling of '\r', '\n' and '\032'.
