/* In Ada, there is no distinction between typedef and non-typedef;
any type declaration implicitly has the equivalent of a typedef,
and thus 't' is in fact equivalent to 'Tt'.
Therefore, for Ada units, we check the character immediately
before the 't', and if we do not find a 'T', then make sure to
create the associated symbol in the STRUCT_DOMAIN ('t' definitions
will be stored in the VAR_DOMAIN). If the symbol was indeed
defined as 'Tt' then the STRUCT_DOMAIN symbol will be created
elsewhere, so we don't need to take care of that.
This is important to do, because of forward references:
The cleanup of undefined types stored in undef_types only uses
STRUCT_DOMAIN symbols to perform the replacement. */
