Subject: [PATCH] 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.

Upstream-Status: Backported [rhel5]
