* Fixed a bug on Mac OS X. Don't require SystemStubs on OS X.
SystemStubs does not exist on Lion. Thank Stefan Karpinski.
* Improved README with using OpenMP. Check the internal threads
count less than or equal to omp_get_max_threads()
x86/x86_64:
* Auto-detect Intel Core i6/i7 (Sandy Bridge) CPU with Nehalem assembly kernels

====================================================================
Version 0.1 alpha2.4
18-Sep-2011
common:
* Fixed a bug about installation. The header file "fblas77.h"
works fine now.
* Fixed #61 a building bug about setting TARGET and DYNAMIC_ARCH.
* Try to handle absolute path of shared library in OSX. (#57)
Thank Dr Kane O'Donnell.
* Changed the installation folder layout to $(PREFIX)/include and
$(PREFIX)/lib
x86/x86_64:
* Fixed #58 zdot/xdot SEGFAULT bug with GCC-4.6 on x86. According
to i386 calling convention, The callee should remove the first
hidden parameter.Thank Mr. John for this patch.
====================================================================
Version 0.1 alpha2.3
5-Sep-2011
x86/x86_64:
* Added DTB_ENTRIES into dynamic arch setting parameters. Now,
it can read DTB_ENTRIES on runtime. (Refs issue #55 on github)
====================================================================
Version 0.1 alpha2.2
14-Jul-2011
common:
* Fixed a building bug when DYNAMIC_ARCH=1 & INTERFACE64=1.
(Refs issue #44 on github)
====================================================================
Version 0.1 alpha2.1
28-Jun-2011
common:
* Stop the build and output the error message when detecting
fortran compiler failed. (Refs issue #42 on github)
====================================================================
Version 0.1 alpha2
23-Jun-2011
common:
* Fixed blasint undefined bug in <cblas.h> file. Other software
could include this header successfully(Refs issue #13 on github)
* Fixed the SEGFAULT bug on 64 cores. On SMP server, the number
of CPUs or cores should be less than or equal to 64.(Refs issue #14
on github)
* Support "void goto_set_num_threads(int num_threads)" and "void
openblas_set_num_threads(int num_threads)" when USE_OPENMP=1
* Added extern "C" to support C++. Thank Tasio for the patch(Refs
issue #21 on github)
* Provided an error message when the arch is not supported.(Refs
issue #19 on github)
* Fixed issue #23. Fixed a bug of f_check script about generating link flags.
* Added openblas_set_num_threads for Fortran.
* Fixed #25 a wrong result of rotmg.
* Fixed a bug about detecting underscore prefix in c_check.
* Print the wall time (cycles) with enabling FUNCTION_PROFILE
* Fixed #35 a build bug with NO_LAPACK=1 & DYNAMIC_ARCH=1
* Added install target. You can use "make install". (Refs #20)
x86/x86_64:
* Fixed #28 a wrong result of dsdot on x86_64.
* Fixed #32 a SEGFAULT bug of zdotc with gcc-4.6.
* Fixed #33 ztrmm bug on Nehalem.
* Walk round #27 the low performance axpy issue with small imput size & multithreads.
MIPS64:

* Imported GotoBLAS2 1.13 BSD version
x86/x86_64:
* On x86 32bits, fixed a bug in zdot_sse2.S line 191. This would casue
zdotu & zdotc failures.Instead,Walk around it. (Refs issue #8 #9 on github)
