88dad06b47 contains a make $(shell)
construct that apparently confuses older GNU make versions (possibly
because of the # inside the shell command?). This construct, which
would allow # comments inside LINGUAS files, was adapted from gettext
recommendations, but we don't actually need that functionality, so
sidestep this whole issue by just using plain "cat".
In passing, make this code work with vpath.

# Common rules for Native Language Support (NLS)
|
|
#
|
|
# If some subdirectory of the source tree wants to provide NLS, it
|
|
# needs to contain a file 'nls.mk' with the following make variable
|
|
# assignments:
|
|
#
|
|
# CATALOG_NAME -- name of the message catalog (xxx.po); probably
|
|
# name of the program
|
|
# GETTEXT_FILES -- list of source files that contain message strings
|
|
# GETTEXT_TRIGGERS -- (optional) list of functions that contain
|
|
# translatable strings
|
|
# GETTEXT_FLAGS -- (optional) list of gettext --flag arguments to mark
|
|
# function arguments that contain C format strings
|
|
# (functions must be listed in TRIGGERS and FLAGS)
|
|
#
|
|
# Also, provide a text file 'po/LINGUAS' with a space-separated list
|
|
# of languages that are provided/supported.
|
|
#
|
|
# That's all, the rest is done here, if --enable-nls was specified.
|
|
#
|
|
# The only user-visible targets here are 'init-po', to make an initial
|
|
# "blank" catalog from program sources, and 'update-po', which is to
|
|
# be called if the messages in the program source have changed, in
|
|
# order to merge the changes into the existing .po files.
|
