| Subject: | Makefile.PL hardcoded for operating systems |

Hi,
I am trying to build Audio::TagLib.
Audio::Taglib requires taglib C++ library, which I have successfully built.
But the Makefile.PL that comes with Audio::TagLib seems to be hardcoded for Unix builds, specifically Macintosh OS-X darwin.
I have included the Makefile.PL below.
Does the Perl standard provide an abstraction layer over makefile creation,
or does each module developer have to hardcode the various compiler/linker commands and switches
in each Makefile.PL?
Any recommendations on converting the Makefile.PL so I can build with Visual Studio 2010 on Windows 7?
Thanks!
Mike
