# This new makefile replaces the previous Makefile/Makefile.linux
# with as much common code for both environments as possible.
# Following is a short OS detection to set up variables, all the
# remaining Makefile should be portable and only depend on these
# variables
#

# Make sure that all is the default target
# (The including Makefile still needs to define what 'all' is)
all:

# Windows' echo echos its input verbatim, on Posix there is some
#  amount of shell command line parsing going on. echo "" on 
#  Windows yields literal "", on Linux yields an empty line
ifeq ($(shell echo ""),)

# This is probably a proper system, so we can use uname
UNAME := $(shell uname)
ifeq ($(UNAME), Linux)
# Linux. (Todo: Add MacOS X if appropriate)
