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.
