But on gcc-4.9 this results in:

symbols.c: In function ‘symbol_entry_find’:
symbols.c:199:3: error: missing initializer for field ‘local_symbol’ of ‘struct symbol_flags’ [-Werror=missing-field-initializers]
   symbol_entry_t needle = { { { }, hash, name, 0, 0, 0 } };
   ^
symbols.c:39:16: note: ‘local_symbol’ declared here
   unsigned int local_symbol : 1;
                ^

So I don't think we should apply your patch.
