[Bug c++/16285] New: cp parser is confused by __complex__

This is somewhat strange:  MinGW fails to bootstrap because of
this problem, but GNU/Linux native does boostrap.  However,
gdb show that the problem is also on GNU/Linux.  The MinGW
boostrap fails when compiling <complex>; here is a stand-alone
"testcase":

$ cat >foo.cc
typedef __complex__ long double myComplexT;
myComplexT foo;
$ gdb $builddir/gcc/cc1plus
(gdb) b grokdeclarator
(gdb) run /tmp/foo.cc -quiet -o /tmp/foo.s
(gdb) cont
(gdb) set debug_tree(declspecs.type)
 <type_decl 0xf6cf81d0 myComplexT
    type <complex_type 0xf6cf8244 myComplexT
        type <integer_type 0xf6dd3740 long int SI
 ...
The type 0xf6dd3740 should be 'long double', not 'long int'.

To clarify:  The testcase can be run on GNU/Linux native;
no need to build a MinGW cross-compiler.

Oops - that's what I get for being behind in reading gcc mail.
(I'm still confused why I didn't see the failure on GNU/Linux native;
probably some version skew.)
I did an update, and am building for MinGW now; it seems to be safely
through with libstdc++.
