PREPROCESSOR DIRECTIVES

  Here are the preprocessor directives that the library understands.

  Some of these are already set up for the OSes with which I am familiar.  See
below for the pre-defined sets.  If you come up with a compiler/platform 
configuration that is not listed here, please send it to me so that i can 
incorporate it into the code base.

  GALIB_USE_ANSI_HEADERS

                      Some operating systems/compilers have old-style headers
                      (e.g. <iostream.h>) while others have new-school
		      headers (e.g. <iostream>).  The default is to use
		      ANSI headers.  If you are using an older compiler,
		      make sure this variable is not defined.

  GALIB_USE_NAMED_TEMPLATES
  GALIB_USE_EMPTY_TEMPLATES
  GALIB_USE_COMP_OPERATOR_TEMPLATES

                      Some older compilers do not require strict, ansi template
		      definitions.  And some compilers require slightly 
		      different ways of specifying templates.  And to make it
		      even more complicated, some depend very much on the type
		      of instantiation method that is defined.  Sigh.

  GALIB_USE_STD_NAMESPACE

                      Some platforms need to explicitly use the std namespace
		      when referring to streams and other std components, but
		      others do not.

  GALIB_USE_STREAMS

                      For systems/environments in which streams are not desired
                      and/or required.  If this is not defined, it turns off 
                      errors and all of the read/write routines for the 
                      classes.

  GALIB_USE_RTTI

                      If your compiler supports RTTI, or if you turn on
                      the RTTI abilities of your compiler, then define this
                      macro.  Without RTTI, if improper casts are made,
		      things will die horribly rather than dropping out in an
		      RTTI-induced exception.

  GALIB_USE_PID

                     Define this if the system has a getpid function that
                     returns something sane and useful.

  GALIB_USE_NO_TEMPLATES

                      For compilers that do not do templates.  The only type
                      of genome available when this is defined is binary 
                      string and any derived classes.  list, tree, and array 
		      all use templates.  You can still use the template code,
		      but you will have to hack it yourself to make it work.

  GALIB_USE_BORLAND_INST

                      For compilers that use the Borland instantiation model.
                      These compilers expect all of the template code to be
		      in the header file.  The Cfront model, on the other
                      hand, expects source files with names similar to the
		      header files, but all of the template code does not
		      need to be in the header files.
		    
		      When you define this flag, the source file that 
		      corresponds to the header file is explicitly included
		      at the end of the header file for all headers that
		      contain templates.

  GALIB_USE_AUTO_INST

                      For compilers that do not do automatic instantiation
                      (such as g++ version 2.6.8) you will have to force
                      instantiations.  When this flag is not defined, GAlib
		      forces an instantiation of all of the template classes
		      that it uses (such as real genome and string genome).

  GALIB_HAVE_NOT_ASSERT

                      Some platforms do not have assert.  So for those
		      platforms we define our own simple version of it.



  USE_GALIB_AS_LIB       For windows shared libraries, one must define whether
  USE_GALIB_AS_DLL       static member data are imported or exported.  You 
                         define one or the other of these, but not both.  The
		  	 default is USE_GALIB_AS_LIB (if you define neither).
			
  COMPILE_GALIB_AS_LIB   If you are compiling the dome library, define one of
  COMPILE_GLAIB_AS_DLL   these to indicate the windows exports.  The default
                         is USE_GALIB_AS_LIB (if you define neither).
 
                
   
  GALIB_USE_RAN1      These specify which random number function to use.  Only
  GALIB_USE_RAN2      one of these may be specified.  You may have to tweak 
  GALIB_USE_RAN3      random.h a bit as well (these functions are not defined 
  GALIB_USE_RAND      the same way on each platform).  For best results, use
  GALIB_USE_RANDOM    ran2 or ran3 (performance is slightly slower than most
  GALIB_USE_RAND48    system RNGs, but you'll get better results).

                      If you want to use another random number generator you
                      must hack random.h directly (see the comments in that
                      file).

  GALIB_BITBASE       The built-in type to use for bit conversions.  This 
                      should be set to the type of the largest integer that
                      your system supports.  If you have long long int then
                      use it.  If you don't plan to use more than 16 or 32
                      bits to represent your binary-to-decimal mappings then
                      you can use something smaller (long int for example).
                      If you do not set this, GAlib will automatically use
                      the size of a long int.  The bitbase determines the
		      maximum number of bits you can use to represent a
		      decimal number in the binary-to-decimal genomes.

  GALIB_BITS_IN_WORD  How many bits are in a word?  For many systems, a word is
                      a char and is 8 bits long.
