[Doxygen-users] Warning: documented function `...' was not declared or defined.

[Yang <ub9...@sn...>]

I'm trying to use doxygen for source browsing, but I get hundreds of 
these warnings:

.../kern/arch/amd64/svm.c:21: Warning: documented function `static 
uint8_t msrpm' was not declared or defined.
.../lib/cppsup/eh_exception.cc:36: Warning: documented function 
`std::exception::~exception' was not declared or defined.
.../lib/cppsup/eh_exception.cc:38: Warning: documented function 
`std::bad_exception::~bad_exception' was not declared or defined.
.../lib/cppsup/eh_exception.cc:42: Warning: documented function `const 
char * std::exception::what' was not declared or defined.
.../lib/cppsup/new_handler.cc:34: Warning: documented function `const 
std::nothrow_t std::nothrow' was not declared or defined.
.../lib/cppsup/new_handler.cc:47: Warning: documented function 
`std::bad_alloc::~bad_alloc' was not declared or defined.
...

AFAICT, the code has no documentation. I'm using doxygen 1.5.3. I 
couldn't dig up much info on this warning message. Any hints would be 
much appreciated. Thanks in advance.
