Hello Charles,

I have a question about the WOE32GCC_SHLIBS conditional:

When a library libfoo contains a public, exported variable 'int data;',
and the library is installed with both shared and static libs (.dll, .dll.a
and .a), then what should the include file libfoo.h contain?

    extern __declspec(dllimport) int data;
is the right thing when a program links to the shared variant (so that the
compiler knows to use _imp__data instead of data itself).

    extern int data;
is the right thing when a program links to the static variant.

But how can the header file know whether the program will link statically
or not?

This matters for libintl, libasprintf and libgettextpo.
