Thanks to all who helped me get gcc installed correctly.

Now I have a new problem.

Apparently, reading in a byte with int istream::get()
will not read past the first occurance of decimal 26,
as it considers that to mean EOF regardless of 
the length of the file.  That wouldn't be a problem
reading in text, but I'm trying to read in a non-text
format, byte-for-byte, and I need to be able to read
the whole file.  Should I be using something other
than fstream, or is there something simple I am
missing to tell the stream to allow binary data?

Here's my source code.  The for loop was originally
a do loop, checking for eof condition, but that
terminated the loop as soon as 26 was read in,
so I tried what follows.  Now every byte starting
with the first 26 is reported as -1.


int main () 
{
     ifstream *infile;

     infile = new ifstream; infile->open("infile2.txt");

     int value;
     int counter;
     int filelen;

     cout << "Length of file (in bytes)?  ";
     cin >> filelen;


     for (counter=1; counter<=filelen; counter++)
          {
               value = infile->get();

               cout << value << endl;
          }


     // Now, clean up.

     infile->close();
     return 0;
  }
