[Bug c/28152] Diagnostic about wrong use _Complex prints __complex__

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-06-28 21:18 -------
Confirmed, we don't record in the preprocessor which keyword is used, _Complex
is treated the same as __complex__.  There is another bug about a similar issue
with "or" and |.

Indeed. However, we can approximate a fix by testing whether we're
compiling under C99, GNU99, or just C90, or C++.

That would not work as _Complex is accepted in GNU90 more and with the C++
front-end by default.
In fact "_Complex float t;" is accepted with the C++ front-end even with
-pedantic which seems wrong and that would be a different but.

Lookup the meaning of "approximation".

This is FIXED for C but not for C++. Probably this is the same bug as 14875 but
just in case, I keep open both.
