One thing that would INCREDIBLY help people trying to help you is find
where the symbol is used, look up the variable types in the function call,
and create a prototype.  For example, both of these are valid xmalloc
instances:
   char *xmalloc(int size);
   char *xmalloc(int size, unsigned char fillvalue)
Seeing the use in the code you are trying to compile will help avoid wrong
answers.

People already likely gave you the answers, but a little leg work on your
own before posting will help.
