[GRASS-windows] Compile r.example for GRASS6.4 in Windows

[António Rocha]

Ok here it goes. Another chapter around the compilation of r.example in 
WINDOWS XP :)

After following Glynn suggestion of changing names of Dll files, I tried 
to run MAKE and I got the following error
The error is
make: Entering directory `/c/grass6/tests/r.example'
c:/grass6/include/Make/Grass.make:418: warning: overriding commands for 
target `/c/grass6/bin'
c:/grass6/include/Make/Grass.make:409: warning: ignoring old commands 
for target `/c/grass6/bin'

-L/c/OSGeo4W/apps/gdal-16/lib -L/c/OSGeo4W/lib     -o 
/c/grass6/bin/r.example.exe OBJ./a/main.o C:/grass6/fmode.o -lgrass_gis 
-lgrass_datetime -lxdr -liberty -lws2_32    -lz      -lxdr -liberty 
-lws2_32    -lz
c:\osgeo4w\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: 
cannot find -lgrass_datetime
collect2: ld returned 1 exit status
make: *** [/c/grass6/bin/r.example.exe] Error 1
make: Leaving directory `/c/grass6/tests/r.example'

There is no file with that name neigter lxdr neither liberty. The this 
is at grass.make DATETIME_LIBNAME is defined:
DATETIME_LIBNAME      = grass_datetime
and then DATETIMELIB is defined as
DATETIMELIB   = -l$(DATETIME_LIBNAME)

so DATETIMELIB is equal to lgrass_datetime and these files doesn't 
exist. My question is: Was it suppose to have those files in Windows or 
they have another name?

Thanks..

Best Regards,
Antonio Rocha
