man2hlp fails on SunOS 5.8

Hello!

fread fails to read large option of data here:

    if (fread (Topics, 1, file_end, fout) != file_end) { 

        perror (output); 

        return 1; 

    } 


errno and ferror is not set. I rewrite this piece of code with
read and even make circle with fgetc, but it does not cure.
It looks like eof, but it is not true.
