join (GNU coreutils) 6.10

gnulib/gnulib-tool: line 1516: echo: write error: Broken pipe
Notice from module localcharset:
  If your package's tests make use of the locale_charset() function directly or
  indirectly, you may need to define the CHARSETALIASDIR environment variable,
  so that "make check" works before "make install". In Makefile.am syntax:
  TESTS_ENVIRONMENT += @LOCALCHARSET_TESTS_ENVIRONMENT@

You may need to add #include directives for the following .h files.
  #include <stdbool.h>
  #include <stdint.h>
  #include "fnmatch.h"
  #include "gettext.h"
  #include "localcharset.h"
  #include "regex.h"
  #include "streq.h"
  #include "uniname.h"
  #include "unitypes.h"
  #include "uniwidth.h"

You may need to use the following Makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
  $(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise

Don't forget to
  - add "src/gllib/Makefile" to AC_CONFIG_FILES in ./configure.ac,
  - mention "gllib" in SUBDIRS in src/Makefile.am,
  - mention "-I src/glm4" in ACLOCAL_AMFLAGS in Makefile.am,
  - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC,
  - invoke gl_INIT in ./configure.ac.
