in Bison. * bootstrap: Update gnulib CVS repository URL. (symlink_to_dir): Encapsulate the code that guarantees the destination directory exists into... (check_dst_dir): ... this new function, and... (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't fail when copying files into lib/uniwidth/. * src/output.c (prepare_symbols): When writing yytname muscles, where symbol names will be encoded in C-string literals, tell quotearg to escape trigraphs. This used to be the default in gnulib. * tests/regression.at (Token definitions): Because of the change in gnulib's quotearg behavior, string_as_id in parse-gram.y no longer escapes trigraphs in symbol names. Thus, yytname no longer has trigraphs unnecessarily doubly escaped. Update test case output. Extend test case to be sure Bison's own error messages will no longer have trigraphs in symbol names unnecessarily escaped once.

Bootstrap this package from the checked-out sources.
|
|
|
|
Options:
|
|
--gnulib-srcdir=DIRNAME Specify the local directory where gnulib
|
|
sources reside. Use this if you already
|
|
have gnulib sources on your machine, and
|
|
do not want to waste your bandwidth downloading
|
|
them again.
|
|
--copy Copy files instead of creating symbolic links.
|
|
--force Attempt to bootstrap even if the sources seem
|
|
not to have been checked out.
|
|
--skip-po Do not download po files.
|
|
--cvs-user=USERNAME Set the username to use when checking out
|
|
sources from the gnulib repository.
|
|
|
|
If the file bootstrap.conf exists in the current working directory, its
|
|
contents are read as shell variables to configure the bootstrap.
|
|
|
|
Running without arguments will suffice in most cases.
