[Mapserver-dev] Building .exes with DLLs on windows

[Yewondwossen Assefa]

Frank,

  I did a couple of tests locally  to be able to have mapserver.dll build.

#if defined(_WIN32) && !defined(__CYGWIN__)
#  define MS_DLL_EXPORT     __declspec(dllexport)
#else
#define  MS_DLL_EXPORT
#endif

and most of the protoypes defined in the .h files are declared using the 
MS_DLL_EXPORT : MS_DLL_EXPORT int msSaveMap(mapObj *map, char *filename);


  The size of the binaries are:

-rwxr-xr-x+   1 fs       None        53297 Apr  7 18:23 legend.exe
-rwxr-xr-x+   1 fs       None       335922 Apr  7 18:23 mapserv.exe
-rwxr-xr-x+   1 fs       None      4137012 Apr  7 18:23 mapserver.dll
-rwxr-xr-x+   1 fs       None      2100568 Apr  7 18:23 mapserver.lib
-rwxr-xr-x+   1 fs       None       473530 Apr  7 18:23 mapserver_i.lib
-rwxr-xr-x+   1 fs       None        53299 Apr  7 18:23 scalebar.exe
-rwxr-xr-x+   1 fs       None        65586 Apr  7 18:23 shp2img.exe
-rwxr-xr-x+   1 fs       None        57394 Apr  7 18:23 shptree.exe
-rwxr-xr-x+   1 fs       None        65586 Apr  7 18:23 sortshp.exe
-rwxr-xr-x+   1 fs       None        69682 Apr  7 18:23 tile4ms.exe

  I have tried locally the mapserv.exe and It seems to run fine.

  I have also modified the windows makefile to be able to switch between 
dll and static modes.

  Not sure If I should go ahead and commit the changes. Any thoughts ?

Later,
