automake: support embedded \# in variable appends Fixes automake bug https://bugs.gnu.org/7610. Use of \# is not portable. POSIX does not provide any way of retaining the # marker in variables. There is wide spread support for \# though in GNU & BSD Make implementations. Today, with plain variable assignments, Automake leaves the line alone: foo = blah\#blah This will leave it to the implementation to decide what to do. But if you try to append to it, Automake follows POSIX and strips it: foo = blah\#blah foo += what -> foo = blah\ what Instead, let's issue a portability warning whenever \# is used, even if it isn't being appended, and do not strip the \# when appending. Now: foo = blah\#blah foo += what -> warning: escaping \# comment markers is not portable -> foo = blah\#blah what * NEWS: Mention change in \# handling. * lib/Automake/VarDef.pm: Do not strip # if escaped. * lib/Automake/Variable.pm: Warn if \# is used. * t/comment12.sh: New test. * t/comments-escaped-in-var.sh: New test. * t/list-of-tests.mk: Add comment12.sh & comments-escaped-in-var.sh.
