+Subject: [PATCH] Replace use of FLT_MAX in x86_64 zscal.c by isinf()
+
+Commit def4996 fixed issues with inf and nan values in zscal,
+but used FLT_MAX, where DBL_MAX or isinf() is more appropriate,
+as FLT_MAX is for single precision only.
+Using FLT_MAX caused test case failures in the LAPACK tests.
+
+isinf() is consistent with the later fix 969601a1
