[antlr-interest] bug in GnuCParser.g - missing declarations and statements

[Andy Tripp]

FWIW, I found and fixed a problem in the "cgram" grammar
GnuCParser.g and StdCParser.g.  They didn't recognize 
declarations coming after statements in a compoundStatement, like this:

f() {
  printf("hello");
  int i;
}

This is allowed in the C99 standard, section 6.8.2, and
by the GCC manual section 5.26 "Mixed Declarations and Code".
