Posting this to libc-alpha per Andreas Jaeger :
>> Steve, I suggest to continue this discussion on

Ran into the following situation ... any ideas, alternatives, or
preferences?

+ "./include/libc-symbols.h" are included before the logical start
+ of this file. Perhaps we need a separate hidden_data_def macro?
+
+ As a temporary work-around, undefine __hidden_def1 and redefine
+ it here, as if HAVE_ASM_GLOBAL_DOT_NAME was not defined.
