New Revision: 1480080
URL: http://svn.apache.org/r1480080
Log:
Latest clang does not emit errors about unknown warning options,
but it does spam the compile output with warnings. Silence those
warnings.
* build/ac-macros/compiler.m4
(SVN_CC_MODE_SETUP): Add -Wno-unknown-warning-option to default C flags.
(SVN_CXX_MODE_SETUP): Likewise for default C++ flags.
