Subject: (Using NON_GNU_CPP): Don't lose if it has spaces.
X-Git-Tag: emacs-19.34~10074
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=63041661ee705febae4a69adeafbf986517da9db;p=emacs.git

(Using NON_GNU_CPP): Don't lose if it has spaces.
If CPP was inherited from environment, don't use NON_GNU_CPP.
(NON_GNU_CC): Likewise.
(handling with_gcc): Use explicit if in the `no' case.
(cc_specified): New variable; if set, don't use NON_GNU_CC.
