#581 Missing com declaration for ITextDocument

[Vincent Richomme]

When compiling poedit with mingw-w64 (the last version provided with msys2) I get the following error:
C:/Developer/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/5.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:/Developer/msys64/mingw64/lib/libWinSparkle.a when searching for -lWinSparkle

collect2.exe: error: ld returned 1 exit status

Makefile:346 : la recette pour la cible « all-recursive » a échouée

It seems the definition of IUnknownPtr is also missing.
