I want to include this header file in a Windows native data transfer file so
that I can map CF_LOCALE clipboard data to a Java text encoding. However, I'm
concerned about the way this file is structured. Because you have defined these
data structures in a header file, each .obj file gets its own copy of these
structures. It would be more efficient to declare these structures extern (and
non-static) in the .h file, define them in a single .c file, and link against
the library which contains the structures when necessary.

The attached test cases show demonstrate the inefficiency. Modify the batch
files to point to a directory which contains locale_str.h. build_locale_1.bat
builds and links a single object file which is empty except for the data
structures in locale_str.h. build_locale_2.bat builds and links two separate
object files, each of which is empty except for the same data structures. The
extra data is enough to increase the size of the DLL by one 4K segment.
