DJGPP pads structs to make all its fields to be properly aligned, so that 
acessing them will be the fastest.  For more details see section 22.9 of 
the DJGPP FAQ list.

Because DJGPP is a 32-bit compiler which produces 32-bit code, whereby an 
int gets 32 bits.

You don't need WWW.  Download the file v2/faq200b.zip from the same place
you get DJGPP and you will have the FAQ (in 3 different formats!) at your 
fingertips.
