I noticed that a straight CVS checkout doesn't quite bootstrap.
Previously, I was getting a successful bootstrap by first running 'ln -s
ltdl libltdl', but that felt hackish. But looking at the output of a
straight checkout gives a clue:
$ ./bootstrap
...
bootstrap: running: libtoolize --ltdl="ltdl" --force --copy
...
libtoolize: Remember to add `LT_CONFIG_LTDL_DIR([ltdl])' to `configure.ac'.
bootstrap: running: autoreconf --force --verbose --install
...
autoreconf: configure.ac: subdirectory libltdl not present
autoreconf: running: libtoolize --copy --force
...
$ ./configure
...
checking if gcc supports -pipe... ./configure: line 6199: -e: command not
found
yes
...
$ make
...
Making all in ltdl
make[2]: Entering directory `/home/eblake/m4-patch/ltdl'
make[2]: *** No rule to make target `all'. Stop.
...
autoreconf didn't quite work, since it was looking for libltdl instead of
ltdl, so make failed. Also, notice the error message when checking for
- -pipe: since configure.ac uses _LT_COMPILER_OPTION prior to LT_INIT, $Xsed
was not defined yet. I don't like using undocumented libtool functions,
but for now, it was easier to just move it after LT_INIT so that it would
at least work.
Meanwhile, note that autoreconf is rerunning libtoolize, which is a slight
waste of time. I will discuss this further in another mail to bug-m4.

* configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
subdirectory to use.
(support for -pipe): Move after LT_INIT, since it relies on
libtool internals.
