Subject: configurator: sometimes _GNU_SOURCE is already defined, in those cases avoid redefinition
X-Git-Url: http://git.ozlabs.org/?a=commitdiff_plain;ds=sidebyside;h=7c077923bccea4f855715c06f06a5df734bc75a0;hp=7c077923bccea4f855715c06f06a5df734bc75a0;p=ccan

configurator: sometimes _GNU_SOURCE is already defined, in those cases avoid redefinition

Config defines are disabled if a warning is emitted (we may want to
reconsider that), and warnings are emitted for define redefinition.
