[boost] Access to unaligned (packed) structs

I am searching for a library / component / pattern that will help me 
with the following problem:

I have a memory structure in raw memory (received from a measurement 
instrument), that is unaligned in its data members.

Now I want to have an access interface to this data that comes as close 
as possible to access of a struct.
E.g.

struct foo {
     char a;
     int b;
}

Altough my raw data "char* pdata" has an 8bit followed by a 32bit I want 
to be able to do something like:

foo data(pdata);

and then

char ch = data.a;
int n = data.b;

Does anyone know about such a library?
(This should work compiler/platform independent of course.)

Thank you,
Roland aka speedsnail
