#
# This script compiles and/or links one or more source or object files into a
# object file or executable target, and outputs all extra dependencies found
# while doing so in a file named target.d, which can be used by GNU Make.
#
# The script should be invoked the same way as your C compiler, that is,
# specifying the target using a -o option and the source or object files as 
# non-option arguments. It will generate dependencies in the form
#
# target target.d: dir/file1.c dir/file2.c header1.h header2.h
# dir/file1.c dir/file2.c header1.h header2.h:
#
# This version is intended for GCC, which can do compilation and dependency
# generation in one step. The name of the GCC version (default gcc) can be
# overridden using the CC environment variable.
#
# CHANGELOG
#
# 2003/1/8: EvB: adapted for gcc 3.2, still handles 2.95 as well.
#
#   This was necessary because gcc 3.2 handles -MD differently than gcc 2.95:
#   where the old version generated a .d file for each source, in the current
#   directory, the new one does almost completely what this script intended to
#   do: generate one .d file in the same directory and with the same file name
#   as the target.
#
#   The only fixups 3.2's .d files still need are:
#
#   - changing the file name; gcc 3.2 strips the suffix of the target before 
#     appending the .d, so targets x and x.o will both produce x.d, which is
#     not what we want;
#
#   - adding the implicit dependencies as prerequisiteless targets, so that
#     make will just consider the target out of date if one does not exist
#     anymore; 
#
#   - adding the .d file as depending on the same prerequisites as our real
#     target so that it will be considered out of date if one of the files
#     mentioned in it are updated or missing.
#
#   Basically, this version does all that by simply including the file
#   <strippedtarget>.d file in the list of .d files we look for. We may end
#   up generating the same file name, but that already was handled correctly.
#   Otherwise we perform the normal routine, so that we /know/ the targets will
#   be correct, directories and all, regardless of variations in gcc behaviour.
