patching versions for UI settings.
Currently four different levels of routines for .blend file reading exist;
/* interface level */
1) BIF_init() -> calls 3
2) BIF_read_file() -> calls 11, optional 4
3) BIF_read_homefile() -> calls 11 or 12, and then 4
4) init_userdef_file()
/* kernel level */
11) BKE_read_file() -> calls 21, and then 14
12) BKE_read_file_from_memory() -> calls 22, and then 14
13) BKE_read_file_from_memfile() -> calls 23, and then 14
14) setup_app_data()
/* loader module level */
21) BLO_read_from_file() -> calls 24
22) BLO_read_from_memory() -> calls 24
23) BLO_read_from_memfile() -> calls 24
/* loader module, internal */
24) blo_read_file_internal()
Note:
- BIF_read_homefile() has additional UI initialize calls, like windows fullscreen and executing commandline options
- Reading from memory (12) only happens for the compiled-in .B.blend
- The "memfile" here is a name I gave to the undo "file" structure. Which is constructed out of memory chunks with basic compression features.
- the kernel function setup_app_data() sets globals like "current screen" and "current scene".
So far, so good. The levels as mentioned here clearly distinguish UI from kernel, and should enable for example game loading (runtime) or background (no UI) loading. In the past years however, 'bad level' dependencies were added, and especially the patches for 'file versions' were added in too many places. The latter is evidently a result of the problem that the "UserDef" struct cannot be initialized/patched if there's not a need for a UI.
Here's how the flow goes in four different cases:
----- Starting up Blender, in foreground with UI --------------------
- creator/creator.c, main() -> calls 1
- If the commandline contains a filename, it calls 11
----- Starting up Blender, in background without UI --------------------
- creator/creator.c, main() -> calls 11 if the commandline has a filename
Note: no Userdef is read, nor initialized. Please note that this was already an existing problem for using Yafray, not setting proper file paths in background mode. The Yafray paths don't belong in the User menu.
----- Starting up Blender as a runtime executable --------------------
This only has calls to 22
----- Loading a file from within the UI (with F1, CTRL+O, using pulldowns) -----
Only calls allowed to 2. It detects if a UserDef has been read too, and in that case the init_userdef_file() will be executed.
Hope this is understandable :)

or whatever):
NAN_NO_KETSJI: when set to true, disables compilation of the game engine.
NAN_JUST_BLENDERDYNAMIC: when set to true, only dynamic executable is
build (i.e., no plugin, etc).
Note that NAN_NO_KETSJI implies NAN_JUST_BLENDERDYNAMIC.
Florian Eggenburger).
Full instructions are in doc/README.windows-gcc.
Main differences from Florian's patch:
- the 'lib' dir should now be the same level as the 'blender' dir (rather
than being a subdir of 'blender'). This is consistent with the other
platforms that bf-blender supports (tuhopuu will also adopt this convention
hopefully soon).
- the script 'free_windows-env.mk' is no longer needed ... see the
docs about how this is overcome (again, tuhopuu will hopefully
also follow this route soon).
- the dlltool dir has it's own Makefile that builds all of the
needed stub libraries from the dll's in cvs.
