This directory contains only RTL parts specific
to the processor I386 family.

(They are specific because they contain assembler instructions)

Include files for system are :
  heap.inc (heap handling)
  set.inc  (sets operations)
  math.inc (mathematic operations using the coprocessor)
  i386.inc (several functions/procedures containing assembler parts)

Units are :
  strings.pp (written in assembler for speed)
  getopts.pp (depends on the way the command line 
              is transmitted to the program)
