Rightly or wrongly, I use "-s -static -Zomf -lc_omf386" at the link stage.
I am not a GCC expert, but the above works for me and produces an executable
which is massive compared to any other compiler, but which has no unexpected
DLL dependencies.

Hi,

very strange, my results are different (for gcc 3.3.5 at least).

Even though I only have one source file I decided to go for a separate
compile and link step:
gcc -Zomf -o lostKingdom.obj lostKingdom.c
gcc -static -Zomf -Zmt -Zmap=lostKingdom.map -Zlinker /STACK:0x10000
-Zlinker /BASE:0x10000 -Zlinker /EXEPACK:2 -lc_omf386 -o lostKingdom.exe
lostKingdom.obj

This gives a VERY SMALL executable which links the C library statically
! It only imports from doscalls.dll, libuni.dll and uconv.dll.

The only problem I have is this warning:
D:\HOME\buildenv\usr\lib\libc_omf386.lib(src/lib/sys/386/signal16bit.asm)
: warning LNK4008: aliased fix-up to non-alias object near F in object
CODE32

However, the executable runs just fine. By the way: Compiling and
linking in one step also does not make a difference.
