	  $(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

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 </cblas.h>
