Subject: Keep CPPFLAGS when building tcl bindings
X-Git-Tag: v1.5.4~3^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a4f4c7e6b1bc38bc91a7275ba634694ccddc1e7b;p=thirdparty%2Frrdtool-1.x.git

Keep CPPFLAGS when building tcl bindings

If CPPFLAGS=-D_FORTIFY_SOURCE=2 during configuration, tcl compilation was not fortified.
This patch adds the missing variable.
