Hi Gabor,
I make a definition file from kernel32.dll by the tiny_impdef.exe and
compile seek.c with tcc ( tcc.exe seek.c kernel32.def ).
The output is:
Size:495
Seems to be is work well...
You probably compiled in 32bit mode.
It does not work on 64bit. Reason is a missing detail in the
calling conventions for x64 windows, that structures of size
1,2,4,8 need to be passed in registers.
The structure in question here is
LARGE_INTEGER liDistanceToMove;
SetFilePointerEx(hFile, liDistanceToMove, ... );
See also x64 windows calling conventions:

Do not expect me personally to fix this.
