CNTK/Makefile

# Makefile for a Linux/GCC build of CNTK
#
# The Linux and Windows versions are not different branches, but rather build off the same
# source files, using different makefiles. This current makefile has the purpose of enabling
# work to make all sources compile with GCC, and also to check for GCC-compat regressions due to
# modifications which are currently done under Windows.
#
# To use this Makefile, create a directory to build in and make a Config.make in the directory
# that provides
