# Be careful when it comes to compiling with -ansi flag on POSIX-like systems!
#
# This might sound strange, but if you compile with '-ansi' you won't get the
# POSIX-dependant features of the whitespace interpreter, which aren't a
# must-have but at least a want-to-have! To make it more clear: wsi tries to
# set the terminal into non-canonical (aka read character by character) mode, so
# that the whitespace scripts gets the chars even before you hit return.

# START OF GNUmakefile ...
#
# GNUmakefile, this Makefile is able to generate dependencies
# automatically. However this requires GNU-style make and 
# a gcc, supporting -M flag.
#
# To generate the common Makefile everything from here on is chopped
# off and replaced by the contents of the *.d files.
