[flac-dev] make dllimport/dllexport attributes work with mingw (and others)

[Ozkan Sezer]

The following patch changes export.h so that the dllimport/dllexport
attributes work with mingw/mingw-w64 and others:
- changes _declspec keyword to __declspec: the former may not be
  defined by some toolchains.
- changes the _MSC_VER condition to universally _WIN32: MSVC, as well
  as GCC supports this.

Attached patch: declspec.diff

Regards.
