Matthew Flatt 23cf3ba11e upgrade pre-built libraries for Windows and Mac OS X
Mostly upgrades the drawing stack to the latest Cairo, Pango, Glib,
etc., but also upgrades the OpenSSL library on Windows to 1.0.1g.

The new "racket/src/native-libs" directory provides scripts to
rebuild the libraries from source. Those script are fragile, because
library sources and configuration scripts are fragile. The
scripts at least archive some expertise/advice in a mostly executable
form.

# This makefile is meant to parse with both normal `make' and `nmake'
# (on Windows). On Windows, prefix each target with `win32-'.
# The targets here do not use dependencies (mostly), so it's a strange
# use of `make'. Really, this makefile is an alternative to a pile of
# scripts, where each target plays the role of a script.

# via $(CONFIG), start server at port $(SERVER_PORT)

# of $(SERVER); result is recorded in "bundle/installer.txt"
