  4. Subject: [PATCH] m4: Only expose what GNU gettext also exposes
  5. Upstream: https://github.com/sabotage-linux/gettext-tiny/pull/67
  7. Otherwise gettext-tiny m4 libs ends up overriding other versions
  8. of vendored gnulib, making autoreconf fail.
  10. Additionally I checked that each m4 file has it's required
  11. automake functions, which can be listed with the following command:
  13.   $ grep AC_REQUIRE m4/*.m4 | grep AM

  1104. -dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
  1105. -dnl libtool).
  1106. -dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
  1107. -dnl programs that really need multithread functionality. The difference
  1108. -dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
  1109. -dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not.
