unfortunately, it turned out that this fix only works when compiling
ada/init.c inside gcc, not for gnatlib where CONST_CAST* isn't defined.
I need the following patch instead, which is also simpler for using
CONST_CAST, not CONST_CAST2, and provides a CONST_CAST definition in
tsystem.h, where it doesn't have to care about non-gcc compilers and
older versions of gcc.
alpha-dec-osf5.1b bootstrap has completed, make check currently
running. Of for mainline if that passes?
Thanks.

gcc:
* tsystem.h (CONST_CAST2, CONST_CAST): Define.
gcc/ada:
* init.c [__alpha__ && __osf__] (__gnat_error_handler): Use
CONST_CAST.
