  * Parse C99 compound statements with mixed declarations and statements
  Rather than the K&R/C89 requirement that declarations precede statements.
  The AST is now a list of eithers rather than two lists.
  Note also that we're now saving and restoring the set of typedef'ed
  identifiers as we enter and leave the scope of the compound statement.
