I have an alpha version of my all-singing all-dancing Makefiles:
<ftp://ftp.shout.net/pub/users/mec/patch/makefile.2126>
Here are some highlights:
separate source and target trees
read-only source tree
can have multiple target trees per source
better makefile structure
auto dependencies with gcc -MD, no more 'make dep'.
command dependencies (automatically recompiles when options change)
make works correctly from subdirectories
much more parallel-friendly
rewritten vmlinux -> zImage commands,
works with binutils 2.5, 2.6, 2.7
works around bug in binutils 2.7.0.2 that bit modules
squeezes empty 4k page out of resident kernel (!)
447 lines of Documentation/makefiles.txt.
Many option settings moved from Makefiles into configuration.
CONFIG_SMP, CONFIG_SMP_PROC.
CONFIG_BOOT_RAMDISK.
VGA boot-time configuration.
And here are some things not done yet:
only architecture is i386
no drivers/sound yet
no genksyms
