X-Git-Tag: accepted/tizen/5.0/unified/20181102.024438~126^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dc8543a4738548dda6f210cca035693e19c7042d;p=platform%2Fupstream%2Fgflags.git

Add test which uses gflags_declare.h.

Update issue 79
Added a test which uses gflags_declare.h as any other project would use it to avoid such avoidable build configuration mistakes.
