User-agent:	KMail/1.13.3 (Linux/2.6.30-2-686; KDE/4.4.4; i686; ; )

Here is an amendment triggered by Ralf observations and suggestions.
It has been quite tricky to get right (hoping that new it's really 
right...).

In the generated scripts wrapping an autotool, I now use the absolute 
path of the wrapped autotool.  This avoids potential spurious failures
and fork bombs (ugh).  This change required the addition of a new and 
quite lengthy shell function to `tests/defs.in': program_abspath().

Also, I added proper "FIXME" comments w.r.t. use of @PATH_SEPARATOR@
for redefinitions of PATH, and switched from `xbin'  to `bin' for the
name of the directory holding the temporary binaries and wrapper
scripts.

Now the tests passes both when $AUTOCONF and $AUTOM4TE are absolute
paths, and when the are simply resp. `autoconf' and `autom4te'.

Regards,
  Stefano
