This function was unused and only the dummy backend implemented it
correctly. Fixing bug 534 will probably require adding this function
back again, but I think it will be easier to do it from scratch than
fix the bogus implementations we had here.
This is necessary when using a POSIX-compliant stdio implementation, which
will set the FILE error flag when input from the pipe is exhausted, causing
all subsequent reads to fail.
This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)
Convert remaining conditional file building to use
OBJS-$(CONFIG_FOO) += foo.o
one problem with reverse meaining (in util/) fixed with local 'hack'.
Cleanup and remove stuff which is now default targets.
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.
Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
