Without the -Wno-typedef-redefinition option, arcmwdt (clang based) complains if a typedef gets redefined in gnu99 mode (since this is officially a C11 feature). While new versions of GCC do not seem to issue this warning in gnu99 mode anymore. So some existing code with typedef redefined which works well with GCC will issue this warning. As this warning is not fatal, so simply shut it off for good. Signed-off-by: Watson Zeng <zhiwei@synopsys.com>
