Ok, with the patch applied, both libtool-1.5.18 and branch-1-5 are
fine: All 112 tests passed.

I must have done something weird; `./boostrap' now works ... and
`./configure' too. But print problems arise with the make command :

gmake[3]: Entering directory `/home/njoly/temp/libtool/libltdl'
source='loaders/preopen.c' object='libltdl_la-preopen.lo' libtool=yes \

Yep ... `print: not found'

The latest looks the best one (#1 and #2 are horrible hacks ;-), and
#3 may have serious effects even on non-libtool aware packages).
