ANSI C permits you to declare variables at the *beginning* of each new block -
but certainly not everywhere within the block. What you did here was mix code
and declarations. The correct sequence is:

{
   /* declarations */
   XRecordRange *rcRange[];
   rcRange[0] = XRecordAllocRange();
   ...

   /* executable code */
   rdcontext = XRecordCreateContext(...);
   ...
}

Thus, either (a) move your declarations to the function beginning or
(b) open a new block with curly braces ( "{" / "}" ) and declare your
new variables at the beginning of this new block.

Be advised, though, that (b) is frequently considered poor programming style -
although this is a matter of personal taste.
