# This script makes it possible to build this package in a sibling directory
# of a package such as GCC, gdb, or binutils, and use the binaries in the
# build tree without doing 'make install'.
#
# Use from within a Bourne-compatible shell:
#     relative_builddir='${top_builddir}/../gettext-runtime'
#     . ${top_builddir}/../gettext-runtime/uninstalled-config.sh

# Note: Another option for the same use-case would be a Makefile target
# 'install-lib', such that the sibling package could do
#     cd ${top_builddir}/../gettext-runtime \
#     && $(MAKE) all \
#     && $(MAKE) install-lib libdir=... includedir=...
# This is how it's done in GNU libiconv. However, the 'uninstalled-config.sh'
# approach has two advantages:
#   - it does not copy artifacts around,
#   - it even allows for Makefile rules to depend on the uninstalled binaries.
# It has also a drawback:
#   - On platforms with weird shared library mechanisms (e.g. AIX, HP-UX,
#     native Windows) it works only with '--disable-shared'.

# Attention! This variable needs to be used _after_ the -I options that ensure
# access to config.h (because INCINTL may contain a -I option that would allow
# access to libintl's private config.h, which you should not use).
