hi,

current trunk doesn't bootstrap ADA with --enable-build-with-cxx.

first problem:

ada/gcc-interface/utils2.c:
  In function ‘int compare_elmt_bitpos(const void*, const void*)’:
ada/gcc-interface/utils2.c:1657:42: error: duplicate ‘const’
ada/gcc-interface/utils2.c:1658:42: error: duplicate ‘const’

quick fix:

diff --git a/gcc/ada/gcc-interface/utils2.c b/gcc/ada/gcc-interface/utils2.c

and right after there's another problem in genertated file:
