Re: LRGEN 9.0: fast LALR parser generator

A user was trying to compile the DFAC code on Linux.
Here is what I took from some code in another product that
compiles on Linux, when DOS is not defined.


            #include <stdio.h>
            #include <string.h>
            #include <ctype.h>
            #include <stdlib.h>
            #include <time.h>
            #include <sys/types.h>
            #include <sys/stat.h>
            #include <string.h>
            #include <fcntl.h>
            #include <math.h>


            #ifdef DOS
            #include <io.h>
            #else
            #include <unistd.h>
            #endif


            #define uchar unsigned char
            #define ushort unsigned short
            #define uint unsigned int


It looks like <io.h> should be <unistd.h> on Linux.


Here is another code piece that might be useful:


            #ifdef DOS
            fd = _open (filename, O_BINARY); // DOS version.
            #else
            fd = _open (filename, 0); // Linux version.
            #endif


About the '_open' warnings. I think on Linux you have to
use 'open' instead.
