As noted on irc we have one .def file that is used for release and maintenance builds. This generated file has all the function names that are published by a .DLL.
If the function is not in the list, we can’t use it in maintainer builds from libraries != libsvn_subr. And if it is in the list, it must be available or the linker will return an error in release mode.

No, that's wrong. The should not be available in non-SVN_DEBUG mode
because nobody should be calling svn_hash__gets directly. All calls
should come from the expansion of the svn_hash_gets macro, which only
expands to the call in SVN_DEBUG mode.
The problem with the "missing prototype" warning should be solved in the
same way we solve it for error tracing (see the definition of
SVN_ERR__TRACING in svn_error.h and how it's used in libsvn_subr/error.c).
