Subject: [PATCH 04/15] Quiet -Wredundant-decls from xorg/os.h fallbacks for
|
||
|
|
new libc functions
|
||
|
|
|
||
|
|
The Xorg headers provide their own versions of strlcat, strlcpy, and
|
||
|
|
timingsafe_memcmp for platforms that don't have them in libc yet, but
|
||
|
|
rely on configure to set HAVE_* defines to determine if they should be
|
||
|
|
defined in the headers.
|
||
