root: fix makefile to run testunity.out

testunity.out is being created in the
root directory and was being called from
the 'all' target incorrectly. This is
now fixed.
Fix: Declare all variables before statements in a function.
     Likewise, place all function prototypes before statements.
     These changes support Microsoft Visual Studio 2008 Express Edition,
       which follows C89-style rules.
