Other alternative compilers:

   open watcom => http://www.openwatcom.org
     Free open source, in active development, complete implementation,
     produces highly optimized code, targets only x86 cpu's.

   gcc-86 =>
       http://git.etherboot.org/?p=people/dverkamp/gcc.git
       http://git.etherboot.org/people/hpa/i86-gcc.git/
       http://www.spinics.net/lists/linux-8086/msg00228.html
       http://raisama.net/gcc-8086/
       http://www.delorie.com/djgpp/16bit/gcc/
     Free open source, unofficial, no development, only tiny memory model,
     produces optimized code, multiple targets.

At these moment, I consider more urgent:

  1. Make ELKS work as expected.
  2. Make C code ansi compliant.
  3. Change assembly code to C wherever possible.
  4. Rearrange files such that at the upper level directories there are only
     C, architecture independent code, and below arch/, all assembly and only
     architecture dependent code.

All these ease targeting other cpu's. I'll try to contribute on these.
