Files contained here are the header and def file for generating a libpdh.a file necessary to access the PDH library from within mingw/msys.

I had to write these, so they are literally just enough for what I was doing with libstatgrab.

To generate the libpdh.a:
# dlltool --as=as -k --output-lib libpdh.a --def pdh.def

Then copy the libpdh.a to /local/lib/ and the pdh.h and pdhmsg.h to /local/include/
