SHARED-FILES

# Files shared with other projects.  Pass a file path to the
# get_glibc_shared_code() function in the python library
# scripts/glibc_shared_code.py to get a dict object with this information.  See
# the library sources for more information.

# The headers on most of these files indicate that glibc is the canonical
# source for these files, although in many cases there seem to be useful
# changes in the gnulib versions that could be merged back in. Not all gnulib
# files contain such a header and it is not always consistent in its format, so
# it would be useful to make sure that all gnulib files that are using glibc as
# upstream have a greppable header.
#
# These files are quite hard to find without a header to grep for and each file
# has to be compared manually so this list is likely incomplete or may contain
# errors.

# patch submitted to the gettext mailing list for changes that could be merged
# back.
#
# This commit was omitted from the merge as it does not appear to be compatible
# with how glibc expects things to work:
