Hi,
Wanting to test Ada on the branch, after checkout I did on x86_64-linux:
../gcc/configure --enable-languages=c,c++,ada --enable-__cxa_atexit
--disable-nls --enable-threads=posix --with-mpfr=/opt/cfarm/mpfr-2.4.1/
--with-gmp=/opt/cfarm/gmp-4.2.4/ --prefix=/n/16/guerby/cxx/install
--enable-build-with-cxx
make bootstrap
...

Given the error is in non Ada-related code I guess this has to do
with the base C++ compiler and system headers in C++ mode, gcc16 is
running Debian 4.0 and GCC 4.1.2 (which works for trunk bootstrap of c,c
++,ada):
gue...@gcc16:~/cxx/build$ g++ --version
g++ (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
gcc16 has a collection of GCC versions:
gue...@gcc16:~/cxx/build$ ls /opt/cfarm/release/
4.2.0 4.2.1 4.2.2 4.2.3 4.2.4 4.3.0 4.3.1 4.3.2 4.3.3 4.4.0
Using 4.2.3 as base compiler failed with the same error as system 4.1.2.
Using 4.3.3 and 4.4.0 as base compiler bootstrap failed on Ada-related
stuff, here gcc/ada/gcc-interface/decl.c:

I guess this has to do with reserved word conflict on "new":
<<
tree
substitute_in_type (tree t, tree f, tree r)
{
tree new;
>>
Do you have some way to deal with this?
Sincerely,
Laurent
