DOS ain't dead - 32-bit MSDOS

32-bit MSDOS (Announce)

Your point seems to be that the FPC library does things, in particular at program start, and that you want it to do almost nothing instead. I think the better answer would be to let your OS implement stub versions of the called API functions. Then you could also run existing FPC Pascal compiled binaries instead of having to recompile the Pascal app source code with your own stripped down runtime library, or having to modify the app source code in question to touch less of the default FPC runtime library. People normally do such things only when they are trying to create VERY small executables, because it will have various side effects beyond doing less calling of the operating system API. So again, you should probably just let your OS provide more API stubs.
