Subject: Default to register_printf_specifier() if no printf hooking #defined
X-Git-Tag: 5.0.1~459
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e0fe9f13eadd6ace435dd9941fa0a998e9324d2;p=thirdparty%2Fstrongswan.git

Default to register_printf_specifier() if no printf hooking #defined

This allows us to build (non-./configured) external tools against
libstrongswan without explicitly specifiying the most commonly used
printf hooking function.
