N869 (C99 draft) 6.7.7 says that typedef names "share the same name
space as other other identifiers declared in ordinary declarators".
So it makes sense that the compiler sees this as an attempt to use the
identifier "a" in two different ways in the same scope.

However, _this_ should work:

  typedef int a;
  typedef int b;
  void foo(void){ b a; }

gcc does accept that, but tcc 0.9.22 does not.  I haven't tried
tcc CVS.
