# I tried to use the autoconf/automake/autolocal/etc (i.e. autohell) tools
# but I just couldn't stomach them. Since this is a Makefile for POSIX
# systems, I will simply do away with autohell completely and use a GNU
# Makefile. GNU make ought to be available pretty much everywhere, so I
# don't see this being a significant issue for portability.
# All commands assume a GNU compiler. For systems which do not use a GNU
# compiler, write scripts with the same names as these commands, and taking
# the same arguments, and translate the arguments and commands into the
# appropriate non-POSIX ones as needed. libs3 assumes a GNU toolchain as
# the most portable way to build software possible. Non-POSIX, non-GNU
# systems can do the work of supporting this build infrastructure.
