Hello,

I'm trying a fat16 library that use an union for storing the
bootsector data, and it seems the compiler doesn't handle correctly
the width of types in memory. 
So I searched some help on crossworks (gcc) compiler and found that I
have to use this attribute with my concerned unions :
 __attribute__ ((__packed__))

But if the compiler doesn't shout at me when compiling , it seems it
has no effect : my union is badly aligned.

Have any idea ?
