So after i ruled out my minor problems with building and get to the ones that are hardly understandable i decided to create this topic.
Building synfig-core i stuck at this kind of error:
I actually have libjpeg installed, but i tried removing it and whole rebuilding after that and still got the same result.
So here’s my build and errors(actually warnings) logs.

Ok i’ve been able to pass through the previous, though for now i building without jpg or png support, but it doesn’t matter, i’ll figure that out later.
Though now i’ve got a strange problem when building synfig-studio: With gtkmm-2.4 i’ve got errors about missing header
“gtk/tooltip.h”, because there’s only header “tooltips.h” in my include gtkmm dir. And when i’ve tried to build with gtkmm-3.0 which actually has header named tooltip.h, i’ve got error about some other header missing 
So can anyone tell me what i’m doing wrong?
Ok sorry for this question, i just didn’t realize that 2.4 is major version, never have any experience with gtk before 
So don’t mind me.
Keep posting your progress. Your jpeg issue sounds awfully familiar. I’m sure I’ve hit this in the past too, but I can’t remember what I did to fix it. I’m searching through old IRC chats (as that’s where I did my brainstorming with Dooglus and Atrus to figure out the Windows build) but so far, not getting any hits.
Predelink, It would be great to correct the wiki recipes meanwhile you’re solving the issues encountered.

I recognized that building synfig-studio without png support is actually useless 'cause it’s trying to make some png out of synfig files during the build.
Getting closer to why AC_CHECK_LIB can’t find my libpng, i’m finding this in config.log:

configure:21325: result: no I read that ‘-no-undefined’ looks unrecognized for gcc-4.6.x. But looks like libtool treats this as i don’t have corresponding libraries. Didn’t figure out what to do with it for now though.
Yeah, i guess i will do it, when i figure my problems out 
Couldn’t say that i figure out the previous problems, but still after compiling synfig-core i’m getting this kind of error:
After some google searching i found out that doing rebase on msys-1.0.dll could help, but after a few tries (i also tried rebasing some other dlls used by synfig.exe) it still gives me the same error. Rebuilding everything is not helping either. The funny thing - if i run the program using gdb, then it’s working just great
Actually i’m at loss, don’t know how to fix this thing, if other problems were mostly problem with configuring and can be fixed at least by fixing config-cache myself, this one looks tough
Uff… i was finally able to build it. It looks like it’s better to stick to gcc 4.5(previous mingw release) and 32-bit system (i’ve build it using virtual machine with 32-bit windows xp). On my native 64-bit windows 7 i keep getting error about cygwin’s heap corruption.
Considering this, looks like not too many changes must be done to current windows build instructions. Though i guess it would be nice to add all the programs and libraries that are essential for building.
Ah - yes. I’m building in a Windows Xp virtual machine under Windows 7. Building directly under Win7 didn’t work for me either. Sorry I didn’t mention that earlier.
