Original patch from: gentoo/src/patchsets/glibc/2.9/6018_all_glibc-ptr-mangling.patch

|
|
|
|
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.
