System: Linux decomino 2.2.17 #1 Mon Sep 4 20:22:16 UTC 2000 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
>Description:
When building on x86 with -mcpu=pentiumpro -march=pentiumpro, GCC
predefines macros including __pentiumpro__ and __tune_pentiumpro__.
However, CVS GCC does not define __i686__ or __i686, which were
defined by GCC 2.95.2. Glibc uses the macro __i686__.
I think the macros __i686__ and __i686 should be defined again when
building for arch=i686, and the macros __i586__ and __i586 for
arch=i586 (in addition to the current __pentiumpro__ and __pentium__
macros).
