Maybe I wasn't clear enough. The USE_GMODULE definition here does not
effect any real G_MODULE concern. It is simply meant (and not named by me)
to statitically include the fileformat filters in the gdk-pixbuf library,
instead of having about >10 additional Dlls like
pixbufloader-(bmp|gif|...).dll.

My statement was: Using single libraries for every fileformat in gdk-pixbuf
does not improve the reuse of binary components, because the
pixbufloader-*.* are *only* usable from gdk-pixbuf. IMO it wold be much
more convenient (if required) to use i.e. a libtiff.dll, which could be
reused by any component which wants the libtiff functionallity.

Another drawback with not included handlers would be (almost) the
requirement of a setup program to get things right. My Dia win32 port
(which currently uses an older version of gdk-pixbuf) has a very simple
installation instruction at the moment: "Simply put the additional
gtk+/system dlls in a place where the dia executable can find it (ie. the
dia\bin directory). Neither Registry entries nor magic configuartion files
required. I'm trying to keeep the whole Gtk+ 2.0 framework that simple as
well.

Please keep in mind that there is no /usr /usr/local /opt - standard on
windoze  like it appears to be on *ix ...

gmodule-win32.c is the appropriate implementation to get gmodule
functionality on win32. It works nice (i.e. the whole Dia plug-in system is
based on it)

My suggestion at the moment: rename USE_GMODULE in gtk\config.h to 
USE_DYNAMICALLY_LOADED_FILEFORMAT_FILTERS_IN_GDK_PIXBUF :-)

1) libtiff.dll was just an example and it's use would require some
standardization on the binary library interface.

2) msvc (= Micro$oft Visual C) will probably not use all the libtool stuff
(or the auto* - breakage), because they (M$) have "invented" all the
windoze-Dll stuff and at the moment it is simply working better using the
native tools. At least if one is willing to use comercial tools at all ...
