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

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.
