Summary: Different compiler for 80386


If the 80386 is running in 8086 mode, as nearly all are,
and running DOS, then MS C 5.0 will generate code that will
run on an 80386 machine. However, if one wants to run the
80386 in protected mode (OS/2), then one needs the OS/2 C
compiler (or the Xenix C compiler if running Xenix, etc.)

The MS's DOS 5.0 C compiler will only generate code for 
8088/86/286/386 machines running in 8086 mode under MS/PC DOS.
