Posix uses various "getconf" calls for compilation flags, library flags, and linking flags. The values returned from the various "getconf" calls are typically command substituted into the program build invocations in the Makefile. I grep-ed all of the installed autoconf files (Debian autoconf 2.57-11) for "getconf", with no matches found. -- Jeff Sheinberg
