+
+When probing for a usable GCC, the existing code already dropped path
+names that contained "c89" or "c90", because these compilers don't have
+the GCC extensions enabled.  This patch also drops names with "c99" in
+them.

+The header file atlas_simd.h contained a syntax error and a few functional
+errors that affected IBM z13.  It prevented any SIMD kernels from being
+compiled successfully for that platform.  This is fixed.  The macro
+vec_madd is avoided, because some GCC versions don't implement it
+correctly; the equivalent GCC builtin __builtin_s390_vec_madd is used

+The probing of the L1 data cache size is sometimes not reliable.  This can

+L1 data cache size can usually be retrieved with sysconf instead, which is
+faster and more reliable.  Do this whenever possible.

+Subject: [PATCH 7/8] Enable "cross-compile"
+
+This adds support for building ATLAS without running any target code.  In
+order for this to work, the archdefs must contain some additional files
+that would otherwise be built during various tuning steps; see the new
+targets extra_get and extra_put in "CONFIG/ARCHS/Makefile".
+
+Even if the archdefs contain these additional files, cross compilation
+is *not* automatically enabled.  To activate it and disable tuning at
+build time, add the option "-Si archdef 2" when running "configure".
