In the vast majority of cases, nothing has changed (i.e. .tgz, .tar.gz,
and .tar.bz2).
EXTRACT_USING_PAX can be set as before.
For custom extractions, instead of using EXTRACT_BEFORE_ARGS,
EXTRACT_AFTER_ARGS and EXTRACT_CMD, simply set EXTRACT_CMD to be the
command needed to decompress and extract the lements from the archive.
${DOWNLOADED_DISTFILE} can be used to reference the distfile(s).
e.g. for compressed shars, where previously there was:
EXTRACT_CMD= ${GZCAT}
EXTRACT_BEFORE_ARGS=
EXTRACT_AFTER_ARGS= |sh
now use:
EXTRACT_CMD= ${GZCAT} ${DOWNLOADED_DISTFILE} | ${SH}
binutils stuff (except gas) to a shared, multiple-target binutils build;
reduce extract and compile times by being more specific with files and
targets; update to egcs 1.1.1 with a diffball from NetBSD's src/gnu/dist
tree; add 4.4BSD a.out archive support to binutils.
