Re: I try compile GCC 7.2.0 68k Version. Get errors "attempt to use poisened". GCC 4.5.0 and older compile with that files. how can this change to work ?

Hello 

In the past i do the GCC 4.3 and 4.5 Ports too, get out of GCC 3.4 files with some changes to work in newer GCC core. m68k-amigaos Target  is in gcc main source configure but some files are miss. 
3.4 Port is done from Gunther Nikl. Gunther or earlier developers add many special non GCC standard features, so i assume the amiga files are not add offical because of not clean code. I do 4.3 and above ports not with Gunther's special feature and some amiga developers change their programs to use this new standard GCC. 

I download source from gcc page and add the platform specific files from old GCC 4.5 to make a newer version. now the 4.5 is old and a new compiler for 68k-amigaos is usefull. 

Is it not possible to change only the Macro FUNCTION_ARG to 

#define FUNCTION_ARG targetm.calls.function_arg

or is syntax complete diffrent ?. question is also since which GCC version this macros do not work ?.
