orange2c and its accompanying libraries are
      intended to be as platform independant as possible.  portability of
      course is limited by the approach to compile orange
      source code to C.  even though C is a fairly widely available
      language, the diversity in system runtime libraries and language
      feature sets is stunning. therefore both the compiler and the base
      libraries are written with portability in mind.  neverthelesse the
      degree of portability depends on a number of facts: | 1.  | both the compiler and the (orange)
        runtime requires a fully working garbage collector.  the system is
        developed using the hans boehm conservative garbage collector
        library which is a transparent replacement for the standard C
        malloc/free function set, and seems to be fairly stable.  even if
        this library is available on a wide range of platforms, the
        non-availability prevends portability of the compiler and libraries
        in the moment. |  | 2.  | the (orange) runtime libraries requires a
        working threading subsystem.  due to the diversity of different
        thread approachs on various operating systems, the language runtime
        kernel needs an special implementation for every new thread
        approach.  only pthread support is available by now. |  
 Supported (tested) platforms and known issuesthe (current) release (0.4.0) has been build and tested
        on following systems: Linux Debian 2.2 (x86)main development platform is linux debian 2.2 (x86).  running
          and compiling on this platforms should be straightforward.
          compiling and running on other linux/x86 distributions should
          raise no special problems.  boehm's garbage collector libraries
          is available pre-compiled and pre-packaged on most
          distributions. FreeBSD 4.4 and 4.5-STABLE (x86)compiling and running both compiler and library raise no
          problemm, but one has to use GNU make instead of the native make
          utility.  either versions 5.3 and 6.0 of boehm's garbage
          collector library has been tested, however it seems that thread
          support is limited in the gc, as the gc's documentation
          tells. SunOS 5.8 (sparc) / Solaris 2.8Compiling and running tools and libraries is straightforward.
          boehm's garbage collector version 6.0 has been tested. BeOS 5 (x86)Earlier versions used to compile and run under this platform,
          but since thread support has been added to the runtime kernel,
          the current kernel code doesn't compile.  boehm's garbage
          collector is no prolem though.  |
