-Original patch from: gentoo/src/patchsets/glibc/2.9/6018_all_glibc-ptr-mangling.patch
-
--= BEGIN original header =-
-http://bugs.gentoo.org/201910
-
-For every arch, PTR_MANGLE and PTR_DEMANGLE defines are in
-sysdeps/unix/sysv/linux/<arch>/sysdep.h. But for alpha this is not true. The
-defines are in sysdeps/unix/alpha/sysdep.h and unix/sysv/linux/alpha/sysdep.h
-includes the first.
-
-This is a patch that fixes the issue and let alpha build, at the expense of
-disabling MANGLING in the non PIC case, but googling showed that the issue is
-known, and that nobody really cares about it. 
-
-Info from: http://sourceware.org/bugzilla/show_bug.cgi?id=5216
