[avr-gcc-list] How to link without .init4 ?

[Bernard Fouché]

Hi.

I'd like to write my own init stuf mainly because I don't have anything 
in .data and I
badly need the few bytes of flash I can spare if I dont bring in the 
application the code
to init .data.

I tried :

avr-gcc ... -nostartfiles

with no luck: all the .init4 stuff is still there but I've lost the 
vector table at the
beginning (__vectors).

Also .init4 is said to be weakly bound (I thought it meant that I was 
able to write my own .init4
function and have its code replace the official one), so I tried to 
write my own section following the
example in the current avr-libc documentation ("Using Sections in C 
code"), I replaced
the .init1 in this example with '.init4'.

I saw my code inserted after .data initialization and before .bss...

Any hint welcome!

Target is atmega64/128 & avr-gcc is 3.4.4, avr-libc is 1.2.5
