This looks like a syntax error in your macros. They get expanded in GCC code 
and the error only happen when the expanded code is compiled. Have a look at 
the positions GCC tells you there are errors at, and check your macros for 
correctness. This is probably a dumb error, like forgetting a ";" at the end 
of a declaration or something.

As for the differences between gcc 2.95 and 3.2, I guess if you redefine the 
poisonned macros as hooks, fix things that don't compile because of obsolete 
macros and add the new macros that are needed, you shouldn't have much 
trouble. Can't help much, since I've started looking at GCC from 3.0.

Macros being updated??

[Roger.Gough]

Hi all,

I am hoping somebody will be able to helpl me with this. I am trying to
target a new architecure using gcc-3.2.2. I am trying to do this by
modifying the target files which were written for gcc-2.95. I understand
these target files and its architecture is similar to my own. I already had
to modify some macros using the target hooks. (thanks Alex for that).
Now however I get the following error with the file c-decl.c. I have an
inkling that it has something to do with a target macro being modified since
gcc -2.95. Anyway this is the error I get:

                 from /home/rgough/gcc-3.2.2/gcc/c-errors.c:22:

What are the differences between gcc-2.95 and gcc-3.2.2. Are these
differences documented and if so where? Thanks for all the help. Any
comments / suggestions would be warmly appreciated.
