Subject: Makefile.in: Automatic generation of dependencies.  Clean doesn't
X-Git-Tag: release-0.50~729
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=79184c78f780cfadd14da58d2b3ea0f237a530f4;p=thirdparty%2Fldns.git

Makefile.in: Automatic generation of dependencies.  Clean doesn't
remove file generated by autoconf, configure, etc.  Use 'realclean'
instead.  Added '-W' option to OURCFLAGS.
