+Subject: [PATCH] Redefine blosc_internal_xgetbv for platforms with immintrin.h
+
+Commit 2f2d876 renamed _xgetbv to blosc_internal_xgetbv.  Commit 0b8608b
+made it conditional to immintrin.h not being included, apparently
+in order to prevent _xgetbv collision.  However, since the block
+no longer defined _xgetbv but blosc_internal_xgetbv, it means that
+the latter is not defined if the condition is false.  #define it to
+_xgetbv to fix missing symbol.
