  Don't run float-x86 tests on Darwin
  
  As hinted by in float-trap.lisp, we don't use x87 FP mode stuff on
  Darwin.  (`floating-point-modes` for Darwin doesn't play with x87
  bits.)  Hence the test in float-trap.lisp doesn't apply to Darwin so
  don't run it.
  
  Add a comment here too.

 (in-package "FLOAT-X86-TESTS")

+;; This tests the floating-point modes for x86.  This works only if we

+;; have the feature :sse2 but not :darwin since darwin has always used

+;; sse2 and not x87.  But see also how FLOATING-POINT-MODES is

+;; implemented in src/code/float-trap.lisp.

+#+(and sse2 (not darwin))
