  -== PREREQUISITES
  +== Prerequisites
   
   * The GNU C Compiler (gcc) is recommended, as the bytecode interpreter takes
     advantage of GCC-specific features to enhance performance. gcc is the standard
  
positive.code:   the C locale (`export LC_ALL=C`) before compiling if you have strange errors
    while compiling OCaml.
  
  * GCC 2.7.2.1 generates incorrect code for the runtime system in `-O` mode on
    some Intel x86 platforms (e.g. Linux RedHat 4.1 and 4.2). If this causes a
    problem, the solution is to upgrade to 2.7.2.3 or above.
  
  * Some versions of GCC 2.96 for the Intel x86 (as found in RedHat 7.2,
    Mandrake 8.0 and Mandrake 8.1) generate incorrect code for the runtime system.
    The `configure` script tries to work around this problem.
  
  * On HP 9000/700 machines under HP/UX 9, some versions of `cc` are unable to
    compile correctly the runtime system (wrong code is generated for `(x - y)`
    where `x` is a pointer and `y` an integer). Fix: use `gcc`.
  
  * Under OS X 10.6, with XCode 4.0.2, the `configure` script mistakenly detects
    support for CFI directives in the assembler. Fix: give the `-no-cfi` option to
    `configure`.

  == Building the compiler
  
  From the top directory, do:
  
          make world.opt
