+#
+# Wrapper Makefile for ncurses library under OS/2.
+# Author:  Juan Jose Garcia Ripoll <worm@arrakis.es>.
+# Webpage: http://www.arrakis.es/~worm/
+################################################################################
+#
+# Notes (from I Zakharevich)
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~
+# I could build the library with the following sequence of commands:
+#
+#   touch Makefile
+#   make -f Makefile.os2 config
+#   make -f Makefile.os2 CC=gcc HOSTCC=gcc CXX=gcc
+#
+# Ignoring the following errors:
+#   Invalid configuration `os2'...
+#   ... ac_maketemp="make": not found
+#   ... syntax error: `done' unexpected
+#   No rule to make target `lib/ncurses4.dll'
+#
+# You may need to run
+#
+#   rm make.defs
+#   make -f Makefile.os2 make.defs
+#
+# if the build of misc/panel.def fails.
+#
+# If you do not have perl, the configuration will fail.  Use autoconf to
+# generate the EMX-specific configure script (see README.emx), and run the
+# configure script to generate the makefiles.  Then, run
+#
+#   make -f Makefile.os2 make.dlls
+#
+# Notes (from J J G Ripoll)
+# ~~~~~~~~~~~~~~~~~~~~~~~~~
+# The `make.defs' rule creates the new '.def' files and outputs a diagnostic
+# about symbols that disappear from one release to the other, as well as
+# checks about the new '.def' consistency.  If there were no problems, the
+# maintainer is free to replace the `.ref' files with the newer ones using the
+# `save.defs' rule.  So, the only tough work is ensuring that the symbols that
+# disappear are not essential.
+#
+# I first thought about killing '_nc_*' symbols, but it seems that some of
+# them --_nc_panel_hook, _nc_ada*, etc-- are needed outside ncurses.dll. 
+# However, the whole size of the export table will not be larger than 1k or
+# so.
+#
+# [installation]
+#
+# The way things are handled in misc/Makefile is not well suited for OS/2,
+# where only emx.src is needed.  Thus, I've written a few wrapper rules in
+# Makefile.os2 that handle installation/deinstallation.
+#
+# [distribution]
+#
+# There's also a new rule that configures and builds a sort of binary
+# distribution, much like the one I prepared for 1.9.9e.  It's `os2dist'.
