[Bug c++/37532] New: [4.4 regression] ICE with decimal floating point data types

[reichelt at gcc dot gnu dot org]

The following code snippet triggers an ICE in the C++ frontend on mainline:

======================================
void foo(_Decimal32) {}
======================================

bug.cc:1: internal compiler error: in write_builtin_type, at cp/mangle.c:1819
Please submit a full bug report, [etc.]

The regression was introduced between 2008-07-05 and 2008-07-12.
Before the code was rejected.

Are these data types supposed to be supported in the C++ frontend or
are they C only? http://gcc.gnu.org/gcc-4.3/changes.html seems to
suggest the latter, but OTOH code like "_Decimal32 d;" compiles fine
with the C++ frontend.
