This error is normal because it's a copy of LIBCmini for GCC 'standard' 
(not ELF).


(I can't compile LIBCmini in ELF format; however, EmuTOS compiles 
perfectly in ELF format.)

Ďakujem Miro :)


I didn't have to change anything; _stksize is set to 64KB.


However, I'm a little disappointed. Given the size reduction with the 
MINTlib targets (-30KB),

I was expecting at least a slight gain with LIBCmini ELF, but it's the 
opposite: the target

sizes increase by 5KB...


                m68k-atari-mint-gcc  m68k-atari-mintelf-gcc
MINTlib  68k         263.988                 235.923
MINTlib  206         244.519                 217.028

LIBCmini 68K          99.134                 104.022
LIBCmini 206          90.999                  95.847


RAM 1Mo              192.940 free            189.856 free


I see that your LIBCmini ELF is quite large:

LIBCmini 4.6.4    96.832

LIBCmini ELF     203.428

Does this affect the program size?


I'll continue using GCC 4.6.4... However, GCC 13.2.0 ELF allowed me to 
fix many errors and warnings in my code.


  Have a good day, Thank you for your help.
