#
# 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
# - this makefile builds an backward compatible DLL. When building with
#   configure you will get a DLL which is compatible only with the 0.10.40
#   and later DLLs of gettext; this makefile builds a DLL which is binary
#   compatible with gettext 0.10.35 (exports by ordinal matter).
# - 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.
#
# If you get unresolved dependencies (e.g. "don't know how to make somefile.h
# which is required for zzz.o) remove (or rebuild, if you have the makedep tool)
# the depend.mak file which contains all the dependencies.
