- Symptom :

When building Cynthiune bundle ID3Tag in MSYS2(mingw32), compiling errors occur. Here are some of logs.

   UTF8String = id3_ucs4_utf8duplicate (ucs4Value);
-----------------------------------------------------------------

- Cause :

All headers exist, but errors appear.

There seems to be conflict between that of <id3tag.h> (ID3Tag library) and "ID3Tag.h" (ID3Tag bundle) due to case insensitve of mingw32 and Windows.

-----------------------------------------------------------------

- Workaround :
MINGW32 ~/gap/user-apps/Cynthiune/Bundles/ID3Tag
$ mv ID3Tag.h ID3Tag0.h
$ svn diff
