* app/gimphelp.c (gimp_help_netscape): Test for help_path being
non-NULL was wrong way.

* app/preferences_dialog.c (file_pref_cmd_callback): Change
"From X Server" to "From windowing system".

* app/makefile.cygwin: Update according to file name changes.

* libgimp/gimp.def
* libgimp/gimpui.def
* libgimp/makefile.{cygwin,msc}: Update for Mitch's and Sven's
changes.

* plug-ins/libgck/gck/gckcolor.c: Include <glib.h> before
gimpmath.h, so G_PI don't get redefined when glib.h is included
later.

From Hans Breuer, portability fixes for MSVC compilation:

* app/dialog_handler.h: Bypass decalration of exported functions
which are marked with G_MODULE_EXPORT in dialog_handler.c when
compiling that file. Otherwise some compilers will get confused.

* app/dialog_handler.c: Define a test macro for above bypass.

* plug-ins/MapObject/mapobject_apply.c
* plug-ins/MapObject/mapobject_image.c
* plug-ins/MapObject/mapobject_shade.c: Include <string.h>.

* plug-ins/flame/flame.c: Define S_ISREG if needed.

* plug-ins/makefile.{cygwin,msc}: Updates.

* plug-ins/sel2path/global.h: Include <stdlib.h>.

* plug-ins/winsnap/winsnap.c: Include libgimp/gimpui.h.
