+Subject: [PATCH 1/1] strtod: fix clash with strtold
+
+Problem reported for RHEL 5 by Jesse Caldwell (Bug#34817).
+* lib/strtod.c (compute_minus_zero, minus_zero):
+Simplify by remving the macro / external variable,
+and having just a function.  User changed.  This avoids
+the need for an external variable that might clash.
