    Description

      The tests for the MMX, SSE ... extensions in the configure script are hardwired for gcc. Since Sun Studio (or Oracle Solaris Studio as it is called now) uses different flags, none of them are enabled by default.

      The attached patch adds the sun studio compiler flags (http://docs.sun.com/app/docs/doc/819-5265/bjasq?l=en&a=view).
      Note the MMX part is suboptimal, as there is no direct flag enabling just MMX in sun studio.
