Warnings for each of functions: openlog( ), vsyslog( ), VARARGS( ),
closelog( )
  warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
  warning: control reaches end of non-void function [-Wreturn-type]
Fixes:
    Explicitly added specification of function type to void for each
      function, suppressing both warnings for each function listed

Warnings:
    warning: incompativle redeclaration of library function 'malloc'
      note: 'malloc' is a builtin with type 'void *(unsigned long)'
    warning: implicit declaration of function 'check_path' is invalid in C99
      [-Wimplicit-function-declaration]
Fixes:
    Removed redeclaration of malloc on line 21
    Included library <stdlib.h> in the code which contains the malloc( )
      function in it's library
    Included scaffold.h header file in the code that contains check-path( )
      function

Warnings:
    warning: implicitly declaring library function 'exit' with type
      'void (int) __attribute__((noreturn))' [-Wimplicit-function-declaration]
    note: include the header <stdlib.h> or explicitly provide a declaration
      for 'exit'
Fixes:
    Included <stdlib.h> in the code which contains the exit( ) function in
    it's library

Warnings:
    warning: implicit declaration of function 'getopt' is invalid
      in C99 [-Wimplicit-function-declaration]
    warning: implicit declaration of function 'atoi' is invalid
      in C99 [-Wimplicit-function-declaration]
Fixes:
    Included the specific function <getopt.h> library to the code
    Included<stdlib.h> to the code which contains the atoi( ) function in
      the library

Warnings:
    warning: implicit declaration of function 'getopt' is invalid in C99
      [-Wimplicit-function-declaration]
Fixes:
    Included<stdlib.h> to the code which contains the getopt( ) function in
      the library
