getting variables in order

[Mike Johnson]

I'd like to define a list of variables as so:

char	a;
char	b;
int	c;
char	d;
char	e[5];
int	f;
char	g;

and have them packed and in order in the map file.

when I do this they are defined in some random order in the map
file.

This is so I can access them as a pointer offset from a to allow
a user to query the state of the vars.

I'm using the AVR version of GCC.

Thanx for any ideas.
