gcc - cygwin - warning: too many 'l' suffixes in integer constant

Hi,
   I have just begun using boost with gcc-3.2 on a vanilla PC-cygwin
platform.  
Up until deciding to use boost I have been compiling with warnings treated
as errors.  
I am getting warning too many 'l' suffixes in integer constant.  See output
below.  
Does anyone know what is going on here?  
The lines in the boost header file of interest use ULL as suffix.  
I presume this is intended to mean unsigned long long though I could not
track down 
the #define (ULL being a rather common string).  
I have discovered that using ull in the preprocessor gives this warning
though it is 
legal when declaring a constant in the language itself.  
This looks like an inconsistency within gcc.
Perhaps because long long isn't officially in ISO C++ yet only C99 (correct
me if I'm wrong).
I managed to remove all but two occurances of the warning by taking the
dubious action of 
changing ull to ul in boost in cstdint.h & limits.h 
but I could not track down the remaining instances.
Are these suffixes necessary for these constants anyway?  
If the constant is big enough to need to be a long long the compiler should
detect that 
and do any promotions necessary before comparison, shouldn't it?  If its
just for buggy compilers (assuming gcc isn't one of them in this case) 
can't ULL be #defined away?  Where can I find this definition?
Apologies for wasting bandwidth with this newbie error but can someone 
recommend a preferred course of action.  
                                Thanks & regards,
                                                     Bruce A.     

(not actually using long longs in this particular application - yet)
