MetaWare of Santa Cruz, CA makes a C compiler called High C which will
compile native 386 code.  You will need a DOS extender to run it, though.

Alternately, you could write some of your code in ASM and turn on the
.386 switch on the assembly.  Interestingly enough, the 386 will
execute 80386 specific 32-bit opcodes even in real mode.  So you
can run programs written this way under normal DOS.  The High C
compiler assumes a protected mode environment with DS=ES=CS=SS,
e.g., a flat address space.
