It is more trivial: it is not implemented. tcc sees the "aligned"
attribute, but there is no code and not even a field to store it
in a typedef.

So basically you need to invent something, such as:
- Store the alignment in the typedef symbol (somehow)
  (that is in decl() at line "if (btype.t & VT_TYPEDEF) {")
- Get it back from a typedef symbol into the attribute
  (that is in parse_btype() at line "typedef_found = 1;")
