No, the static libfribidi.a should define them without the __imp_
prefix which is special to shared Dlls. The compiler generates
references to them if a function declaration is annotated with
__declspec(dllimport). For FriBiDi, this decision happens in fribidi-
common.h where FRIBIDI_ENTRY should be '#define'd away if
FRIBIDI_LIB_STATIC is defined, which is injected from
pkgconfig/fribidi.pc.

So the question is how you end up *not* having those defines. Are you
building from scratch (ie, mingw/ removed) with the exact scripts from
master or my latest merge request?
