I've pushed a few changes to bootstrap:
boostrap: indent only with spaces
* build-aux/bootstrap: Indent only with spaces, never TABs.
bootstrap: split long lines
* build-aux/bootstrap: Keep line length < 80.
bootstrap: sync from coreutils
* build-aux/bootstrap: Honor variables like $ACLOCAL, etc.,
just as autoreconf does. Verify a list of prerequisite
package-name,version-number pairs if defined in bootstrap.conf.
Refer to README-prereq, if prerequisites are not satisfied.
That latter happens only if README-prereq exists, of course.
For example, here's the "buildreq" list from coreutils' bootstrap.conf:
# Build prerequisites
buildreq="\
autoconf 2.61
automake 1.11
autopoint -
bison -
gettext -
git 1.4.4
gperf -
gzip -
makeinfo -
perl 5.5
rsync -
tar -
In case you weren't following bug-coreutils traffic when this went in,
users of ./bootstrap appreciate learning about it right away --
and getting the full list -- when prerequisites are not met.
Otherwise, they learn about problems piecemeal, sometimes via obtuse
diagnostics, as succeeding stages of the build process fail.
