Hi all, when cross-compiling from Linux for Windows using MinGW, it complains about some missing include files in the MMDevice API. Namely the include directives for 'Guiddef.h' and 'FunctionDiscoveryKeys_devpkey.h' should be changed to lower case, to allow MinGW to find them on case sensitive file systems. Additionally, the aconfigure.ac target for MinGW/Win32 is missing the required 'unicode_win32.o' object file in its 'ac_os_objs' list. Regards Tobias Schlager
