[gdal-dev] nmake.opt compile rule changes

[Frank Warmerdam]

Folks,

If you don't build on Windows using visual studio NMAKE files you can stop
reading.

I have removed the .cc.obj and .c.obj rules from the nmake.opt and ensured
that CPPFLAGS gets set so that the default NMAKE rules for compiling can get
used.  The advantage of this is that they will build all the source files in
one makefile/directory in a single invocation of the compiler instead of one
invocation per file.  This can substantially speed up large builds.  Building
the gdal/port directory went from 30s to 15s for me.

If you have build problems on windows in the near future consider that my
change may be the cause.
