Subject: Avoid MinGW-w64 strndup compiler warning
X-Git-Tag: v1.7.2~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1c231bf6dc84160b7c1aed4a3fd04063164e120a;p=thirdparty%2Frrdtool-1.x.git

Avoid MinGW-w64 strndup compiler warning

- Fixes the following MinGW-w64 GCC compiler warning:
  rrd_create.c:287:14: warning: declaration of 'strndup' shadows a
  built-in function [-Wshadow] static char *strndup(
- MinGW-w64: strndup is not detected by configure, therefore
  HAVE_STRNDUP is not defined.
  Use strndup_() here instead of strndup() to avoid any collisions.
