WS6U2 (32-bit mode): long long bitfields are not allowed

Question

The C++ README for WS6U2 states:
(in Sun Workshop 6 New Features)
"The restriction on the size of a bitfield to 32 or less is removed. Bitfields can be any size."
but if we use this code:
// spam.cc begins:
struct spam {
..unsigned long long a : 40;
..unsigned long long b : 20;
spam empty_spam() { return spam(); }
// ends
[note: i've used "."'s because leading spaces seem to be ignored; and the "special tokens" url (goes to FAQ) doesn't go to a helpful page]
and attempt to compile on a Solaris 2.6 machine:
$ CC -c spam.cc
"64-bit-fields.cc", line 2: Error: long long bit fields are not allowed.
"64-bit-fields.cc", line 3: Error: long long bit fields are not allowed.
2 Error(s) detected.
$
it even fails on Solaris 2.8, with CC -xtarget=ultra -xarch=v9a -c spam.cc
if we change the "long long" to "long" it will compile on Solaris 2.8 (with -xtarget=ultra -xarch=v9a) and use 64-bit long's.
it hardly seems that "bitfields can be of any size".
