If you use a gcc compiler, then you can solve this problem by using -m32 option.
"-m32 option" means that "Generate code for a 32 bit".
It does not need any modification of source.
I have ever built microwindow on 64 bit machine with -m32.
It works well.

: I've came to a conclusion, that it
: has to do with the fact that i've compiled it on 64 bit architecture.
You're right!
: 1) Why is there a new define of DWORD in image_bmp.c? Would be better
: to include windef.h, right?
Yes. Or at least not redefine and use DWORD. I'll look into
this, I'm not sure yet that I want windef.h to be a dependency
in the api-independent engine/ source.
: 2) Maybe it would be better to define 64 bit architecture in config?
: Something like X86_64_BIT?
Actually, someone has already produced a patch for 64 bit
compiles, which do not require any config requirement.
I had held off on this because of the need to move
to the u_int_32 typedef's etc. I think its perhaps time
to patch the source with these updates. They involved
many changes, as the current source pretty much has
assumed sizeof(long)=32.
