   Hi,   
      
   I'm developing since 1987 a shareware called Eureka 2.12 on different   
   successive ATARI computers, and since GNU/GCC 2.8.1 was released, I   
   also use that C language compiler under freeMiNT, the ATARI free OS.   
      
   My C sources are perfectly compatible with GNU/GCC until 3.3.6 version.   
   But since GNU/GCC 4 optimizing compiler is available, I can't build my   
   sources successfully. Large parts of what it's written in C language   
   are completely discarded from the binary even if I use the "-O0" option.   
      
   Is there a way to force GNU/GCC 4 (I'm experimenting 4.6.4 version) to   
   build strictly what it is written in C, preventing from optimizations ?   
      
   For the moment, the Eureka 2.12 software can be built, but the binary   
   is not corresponding to sources, and is totally misbehaving with   
   GNU/GCC 4, because my sources are misinterpreted. GNU/GCC 3 is correct.   
      
   I was imagining that C language is offering sources compatibility, but   
   since the fourth version of GNU/GCC, it isn't the case apparently with   
   my old sources. The problem seems to be caused by the compiler itself,   
   and not the corresponding libraries, because I even tested GNU/GCC 4   
   with the exact same libraries than with GNU/GCC 3 ...   
      
   Thanks in advance for helping me.   
      
   Best regards,
