Subject: define _DEFAULT_SOURCE alongside _BSD_SOURCE
X-Git-Tag: v1.5.3~3^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F615%2Fhead;p=thirdparty%2Frrdtool-1.x.git

define _DEFAULT_SOURCE alongside _BSD_SOURCE

_BSD_SOURCE deprecated since glibc 2.20 and _DEFAULT_SOURCE should be used
instead. Define both to fix deprecation warning.

Quoting the man page feature_test_macros(7):
Since glibc 2.20, this macro is deprecated.  It now has the same effect as
defining _DEFAULT_SOURCE, but generates a compile-time warning (unless
_DEFAULT_SOURCE is also defined).  Use _DEFAULT_SOURCE instead.  To allow
code that requires _BSD_SOURCE in glibc 2.19 and earlier and _DEFAULT_SOURCE
in glibc 2.20 and later to compile without warnings, define both _BSD_SOURCE
and _DEFAULT_SOURCE.
