Browse source 
- fixed configure.in to compile WASAPI module under MSYS
- fixed include name cases for case-sensitive build environments
- defined LPCGUID for some MinGW compilers which are missing it
- fixed strict-aliasing rules break on line of getting device EndpointFormFactor in case '-Wstrict-aliasing' is specified or corresponding GCC optimization flag is used
