0005 #  LIBEXECINFO_INCLUDE_DIR - Libexecinfo include directory

0008 # TODO: This will enable translations only if Gettext functionality is
0009 # present in libc. Must have more robust system for release, where Gettext
0010 # functionality can also reside in standalone Gettext library, or the one
0011 # embedded within kdelibs (cf. gettext.m4 from Gettext source).
