Re: [cc65] library path

Hi Greg,

For example:

toplevel make/gcc.mak:

CC65DATA	= $(libdir)/cc65
CC65INC		= $(CC65DATA)/include

cc65/make/gcc.mak:

CC65_INC = \"/usr/lib/cc65/include/\"

Each of these lines has a reason for being like it is, but all in all
it looks like different strategies in the same project.

I made a small demo for that. In addition to how the quotes are given
to echo please also note how make functions like $(dir) work when
there are quotes and when there aren't. That's why I prefer not to use
quotes inside path variables. Only add them when needed in a command
line, e.g. behind -D for string macros.

========================
$ cat Makefile

WITH_QUOTES=\"foo/bar\"
WITHOUT_QUOTES=foo/bar
NO_ESCAPE="foo/bar"

..PHONY: all
all:
  echo $(MAKEFILE_LIST):
  echo "WITH_QUOTES: >$(WITH_QUOTES)<"
  echo "WITHOUT_QUOTES: >$(WITHOUT_QUOTES)<"
  echo "NO_ESCAPE: >$(NO_ESCAPE)<"
  echo "dir WITH_QUOTES: >$(dir $(WITH_QUOTES))<"
  echo "dir WITHOUT_QUOTES: >$(dir $(WITHOUT_QUOTES))<"
  -echo "dir NO_ESCAPE: >$(dir $(NO_ESCAPE))<" # <= fails!
  echo
  $(MAKE) -f Makefile.sub WITH_QUOTES=$(WITH_QUOTES)
WITHOUT_QUOTES=$(WITHOUT_QUOTES) NO_ESCAPE=$(NO_ESCAPE)

========================
$ cat Makefile.sub

WITH_QUOTES=\"default"
WITHOUT_QUOTES=default
NO_ESCAPE="default"

..PHONY: all
all:
  echo $(MAKEFILE_LIST):
  echo "WITH_QUOTES: >$(WITH_QUOTES)<"
  echo "WITHOUT_QUOTES: >$(WITHOUT_QUOTES)<"
  echo "NO_ESCAPE: >$(NO_ESCAPE)<"

========================
$ make -s

Makefile:
WITH_QUOTES: >"foo/bar"<
WITHOUT_QUOTES: >foo/bar<
NO_ESCAPE: >foo/bar<
dir WITH_QUOTES: >"foo/<
dir WITHOUT_QUOTES: >foo/<
/bin/sh: -c: line 0: unexpected EOF while looking for matching `"'
/bin/sh: -c: line 1: syntax error: unexpected end of file

Makefile.sub:
WITH_QUOTES: >foo/bar<
WITHOUT_QUOTES: >foo/bar<
NO_ESCAPE: >foo/bar<
