#38271: gsl @1.15_2: AVX should be disabled for variant +optimize
----------------------------+--------------------------------

     Type:  defect          |     Status:  new
 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:  2.1.3
 Keywords:                  |       Port:  gsl
----------------------------+--------------------------------
 Because an assembler provided by ccutils has not supported AVX
 instructions, all versions of gcc cannot compile a binary with AVX
 enabled. As a result, gsl cannot be build on Sandy-bridge or Ivy-bridge
 systems when the variant optimize and one of the gcc variants are enabled.

 Here is a patch that disables AVX for variants +gcc44, +gcc45, gcc46 and
 gcc47. The AVX support was implemented from gcc 4.4
 ([http://gcc.gnu.org/gcc-4.4/changes.html release note of gcc 4.4]), so I
 suppose it does not affect gcc43 variant.
