Subject: tests: loosen/tighten the always_defined_macros check
X-Git-Tag: v8.6~182
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6ac165922c9874246034352ee87b1e40ccfec11c;p=thirdparty%2Fcoreutils.git

tests: loosen/tighten the always_defined_macros check

* cfg.mk (.re-defmac): Generate better regexps: allow white space
before the '#', and append a word-boundary requirement.
Without the latter, #define NULL_DEV ... would evoke a false-positive.
