Undefined Symbol problem

Hi, I am working on a C program and I got the following function:

Code:

int printCount(char* fileName)
{
        struct Node* current;
        current = head;
        int unique = 0;
        int total = 0;

        printf("filename: %s\n\n", fileName);
        printf("COUNT | WORD\n");
        printf("------+------------------\n");
        while (current)
        {
                unique +=1;
                total +=current->count;
                
                printf("%5d | %s\n", current->count, current->word);
                current = current->next;
        }
        printf("\n\n");
        printf("Number of Unique words found in %s is %d\n", fileName,
               unique);
        printf("Total number of words in %s is %d\n", fileName, total);
}

I am compiling this code with the SUN cc compiler and it gives me the following errors on these lines:

' int unique = 0;'
syntax error before or at: int

'unique +=1;'
undefined symbol: unique

'total +=current->count;'
undefined symbol: total

'printf("Number of Unique words found in %s is %d\n", fileName,
unique);'
undefined symbol: unique

'printf("Total number of words in %s is %d\n", fileName, total);'
undefined symbol: total

When I compile this program with the Unix gcc compiler it doesn't give me any errors, but as soon as I compile it with the cc compiler it throws me those "undefined symbol" errors. Does anyone know why?

Thank you.

Could it have anything to do with the fact that you don't declare those variables before you assign something to current?

Code:

current = head;

Where has head come from? I'm assuming it's a global var...
