- Subject: [PATCH] Make rs6000 port bootstrap using G++ as 2nd/3rd stage compilers
I tried building the powerpc64-linux compiler today, and it would not
bootstrap, since evidently stages 2 and 3 are built with G++ instead of C, and
G++ is more strict about const pointers.
This patch allows the compiler to bootstrap. Is it ok to install?

* config/rs6000/rs6000.c (rs6000_xcoff_strip_dollar): Rewrite to
avoid warnings when GCC is built with a C++ compiler.
