* Detect LLVM/Clang compiler. The default compiler is Clang on Mac OS X.
* Change LIBSUFFIX from .lib to .a on windows.

x86/x86-64:
* Optimize c/zgemm, trsm, dgemv_n, ddot, daxpy, dcopy on
* 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:
* Fixed #28 a wrong result of dsdot on Loongson3A/MIPS64.
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)
