[boost] wave lexed_tokens sample gives an unexpected answer

Hello,

I built the Wave preprocessing lib out of CVS head today using GCC 4.2.1
on Linux x86 box (openSUSE 10.3).  I then built the lexed_tokens sample
and ran it on the attached header file.   The unexpected answer was how
the 'defined' keyword was treated.  I expected it to treat it as
T_DEFINED, but it seems to return T_IDENTIFIER as shown by this output
fragment:

...
PP_IF            (#370) at foo.h (  4/ 1): >#if<
SPACE            (#393) at foo.h (  4/ 4): > <
IDENTIFIER       (#381) at foo.h (  4/ 5): >defined<
SPACE            (#393) at foo.h (  4/12): > <
IDENTIFIER       (#381) at foo.h (  4/13): >BAR<
NEWLINE          (#395) at foo.h (  4/16): >\n<
...
