General remarks on compiling (may not apply to all programs):

 - No default optimization option is used in the Makefile since this is
   compiler dependent. One has to find out what option produces the best
   result on the platform. Check the manual of your C-compiler for more
   information. The variable COPTIMIZE is reserved for optimization.
   For some systems I have experience with optimization options are
   given at the beginning of the Makefile, uncomment them for your system.

 - To compile with additional options, you can use the variable "CCOPTIONS"
   in the Makefile. You may change the behaviour of make on the fly by
   entering

       make "CCOPTIONS=-option ..."

   which should work for most "make" commands. Otherwise set it manually
   in the Makefile or use an environment variable.

 - Similarly, additional link libraries may be set using the variable
   "LDOPTIONS".

If you encounter problems when compiling this package, some hints:

 - If you don't have an ANSI-C compiler, get one (for example GNU-C)
   or forget about this program (it uses prototyping with ANSI-C style
   prototypes, so a K&R compiler won't work). I do *not* support ancient
   K&R compilers.

 - If your compiler conforms to the POSIX standard but refuses to compile
   certain routines, try calling make with

       make "CCOPTIONS=-D_POSIX_SOURCE"

   or some option that defines the constant "_POSIX_SOURCE" for the
   preprocessor. This option should force your compiler to resort to pure
   POSIX mode and disable any non-POSIX extensions.

 - If you are still not able to compile or if your compiler does not adhere
   to the POSIX standard, you can prevent the usage of any POSIX functions
   at all with

       make "CCOPTIONS=-DCONFIG_NO_POSIX"

   Then the code conforms to the ANSI standard. This does not work for some
   of my programs where POSIX capabilities are required to work at all.
