Need help with lab homework:

# Makefile:
#        It uses the C++ Compiler with all warnings and
#        full debugging; will create a single executable called 'main'
# ---------------------------------------------------------------
# Note: If you want to use the g++ compiler on pegasus or helios
# uncomment the g++ lines and comment the Digital Unix lines

# the Digital Unix C++ compiler needs these lines:
CPP = cxx
CFLAGS = -L/usr/lib/cmplrs/cxx -DPOSIX_4D9 -w0 -gall

# the g++ compiler on pegasus and helios needs these lines:
# CPP = g++
# CFLAGS = -DPOSIX_4D9 -w -g

# link in the math library
LFLAGS = -lm

RM = rm -f
# ----------------------------------------------------------------
# Explanation of macros:
#     $< is any dependent file which is out of file1
#     $* is the target's basename (without extension)
#     $@ is the target's fullname
#
# add suffix .cpp since it is not a default with make util
.SUFFIXES:     .cpp .o
#
# implicit rule for compilation only:
.cpp.o:
     :{CPP} -c ${CFLAGS} $<

OFILES=          main.o

# dependencies
#
default:     main    
#
main:           $(OFILES)
     {CPP} ${CFLAGS} ${LFLAGS} $(OFILES) -o $@

main.o:          main.cpp

#
clean:
     ${RM} *.o
     ${RM} core
#
veryclean:     clean
     ${RM}  main  

#include <iostream>  
using namespace std;

#define CHUNK_SIZE 100

template <class item_t>
class Stack_t

    ~Stack_t() { delete [] items; }
    void push(item_t item)
    {
        if (top%CHUNK_SIZE == 0)
        {
            item_t* nitems = new item_t[top + CHUNK_SIZE];
            if (items != NULL)
            {
                for (int i = 0; i < top; i++)
                    nitems[i] = items[i];

            if (top > 0)
            {
                nitems = new item_t[top];
                for (int i = 0; i < top; i++)
                    nitems[i] = items[i];
            }
            delete []items;
            items = nitems;
        }
        return true;
    }                            
    bool empty() { return top == 0; }
};


int main()
{
    const int SIZE = 100;
   
    Stack_t<char> S;
    char input[SIZE]    = { 0 };
    char S_output[SIZE] = { 0 };
    int i,length;
   
    cout << "Enter a palindrome> ";
    gets(input);
    for(i=0;input[i]!=NULL;i++)
    {
        S.push(input[i]);
    }
   
    length = strlen(input);  
    for(i=0;i<length;i++)
    {
        S.pop(S_output[i]);
       
        if(input[i]!=S_output[i])
        {
            cout << endl << "The words are not palindrome" << endl;
            break;  
        }
       
        else // if(Q_output[i]==S_output[i])
            cout << S_output[i];
    }
    if (i >= length)
        cout << " is a palindrome" << endl;
   
    putchar('\n');

    Stack_t<int> Si;
    int inp;
    cout << "Enter a list of integers terminated by -1" << endl;
    for (i = 1; ; ++i)
    {
        cin >> inp;
        if (inp == -1)
            break;
        Si.push(inp);
    }

    int sum = 0;
    while (!Si.empty())
    {
        Si.pop(inp);
        sum += inp;
    }
    cout << "The sum of the numbers entered is " << sum << endl;
    return 0;
}

output:

I am not terribly familliar with make files but this looks iffy:

     :{CPP} -c ${CFLAGS} $<

I'd suspect it should be

     {CPP} -c ${CFLAGS} $<
