Subject:	Sizeof structure different in DJGPP?

Hello

I seem to come up with a new question every day almost, but here goes!
I have a structure as follows in my program :

struct something
{
   char ch;
   unsigned short int number;
};

In Turbo-C the sizeof this struct is, as expected, 3 bytes. In DJGPP 
it is 4 bytes ???! The sizeof (char) and sizeof (unsigned short int) 
is 1 & 2 respectively in both compilers... Does DJGPP Word-align data,
promoting the 3-byte strucure to 4 bytes? The reason I am asking is 
that I want to store many (60,000) such structs in an array, and 
wasting 60Kb+ in DJGPP seems crazy, even though memory is no problem. 
I want to avoid paging on small systems unless absolutely 
neccessary (sp?), so the extra 1 byte is irritating me...

Thanks for an informative mailing list!
Mark.--
