In about 2002, we compared the codesize for the FreeDOS kernel
produced by TC 2.01, TC++, Watcom, MS VC 1.52, Digital Mars

TC/TC++ were largest, then MS VC (~85%), then Watcom (~80%)
Digital Mars didn't compile straight due to some crazy macros/far pointer arithmetik, but would probably ended up at ~88%

Watcom allows also some funny inline assembler functions, so with a couple of #ifdefs the watcom kernel is now a few percent smaller.

If only size matters, Watcom is the best compiler around for DOS Kernel type of project.
OTOH MS VC 1.52 produces better code for 386 CPUs and DWORD operations; so your milage may vary
