# OS/2 GNU Makefile for building gettext with GNU Make and GNU C compiler
#
# OS/2 still supports the regular configure/make building mechanism, but its
# way more clumsy, complicated and error prone. It is highly recommended to
# use this makefile instead, because :
# - this makefile builds an optimized static and dynamic version of the
#   library
# - it is able to build both optimized and debug versions of the library
#   without any reconfiguring
# - it is able to generate a complete OS/2 binary distribution (make distr)
# - besides its simply alot faster than configure generated makefiles
#
# The makefile is designed to be more or less gettext version independent,
# so it is likely to work with future versions of gettext as well. However,
# please inspect the pre-built config.h file (if you haven't built one with
# configure) so that VERSION macro contains the correct value.
