[avr-gcc-list] array of structures with variables in flash

Hi All,

I have an array of structures in global space and would like access 
these structures from within my code. The structure is declared as 

struct {
        PGM_P name;
        const uint8_t no_of_param PROGMEM;
        PGM_P parameters;

On compile i get the warning;
"warning: `__progmem__' attribute ignored"

How do i declare variables (not strings) to be placed in ROM?

Now for the second part of my query (which is probably not avr specific 
but C in general), how do i declare the prototype for the above 
structure to be included all my project files?

I would like to use the index variable as an identification and do a one 
time initialisation. something like this;

#define XYZ 3

command[XYZ].name = PSTR("Something");
command[XYZ].no_of_param = 5;

While the above statements are going to be in the same file as the 
structure, say global.c, i want the structure to be accessible in other 
files like this;

length = strlen_P(command[XYZ].name);

Thanks in advance.
