Hello!

The configure script of (lib)m17n-lib 1.5.4 is buggy and fails at =20
line #32967. The report was unclear or misleading (I found that the =20
function PKG_CHECK_MODULES() does not seem to be defined), so I tried =20=

to run it in a *compilation* buffer as 'sh -x ./configure' =96 and =20
after twelve hours it hasn't finished. Within minutes it finished in =20
GNU Emacs 21.3.50 and 22.3 =96 and also in *shell* buffer in GNU Emacs =20=

23.1.50. In the *compilation* buffers of GNU Emacs 23.0.60, 23.0.94, =20
and 23.1.50 the progress is slower than a snail when the script tries =20=

in a loop to determine the maximal length of command arguments. =20
"Words" with a length of a few K obviously cause this stop.

For the test I launched all five Emacsen with -Q, opened the prepared =20=

copy of the original directory in dired-mode, invoked M-x compile RET =20=

and changed the default 'make -k' into 'time nice +19 sh -x ./=20
configure' without pressing RET at once. After all lines were =20
prepared in mini-buffer I pressed RET in each.

The GNU Emacsen 23.x are all not really responsive (the system is, I =20
can move around the frames, I can resize them, but the windows do not =20=

refresh), changing to the other window works, but reaching the end of =20=

the buffer might succeed tomorrow. When GNU Emacs 23.1.50 was running =20=

with all my customisation, the time in mode-line was updated in =20
intervals of around 10 min.

GNU Emacs 23.0.60 refreshes fastest=85

Without vi there is only GNU Emacs
