The configure script of (lib)m17n-lib 1.5.4 is buggy and fails at line #32967. The report was unclear or misleading (I found that the function PKG_CHECK_MODULES() does not seem to be defined), so I tried to run it in a *compilation* buffer as 'sh -x ./configure' – and after twelve hours it hasn't finished. Within minutes it finished in GNU Emacs 21.3.50 and 22.3 – and also in *shell* buffer in GNU Emacs 23.1.50. In the *compilation* buffers of GNU Emacs 23.0.60, 23.0.94, and 23.1.50 the progress is slower than a snail when the script tries in a loop to determine the maximal length of command arguments. "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 copy of the original directory in dired-mode, invoked M-x compile RET and changed the default 'make -k' into 'time nice +19 sh -x ./ configure' without pressing RET at once. After all lines were prepared in mini-buffer I pressed RET in each.

The GNU Emacsen 23.x are all not really responsive (the system is, I can move around the frames, I can resize them, but the windows do not refresh), changing to the other window works, but reaching the end of the buffer might succeed tomorrow. When GNU Emacs 23.1.50 was running with all my customisation, the time in mode-line was updated in intervals of around 10 min.

GNU Emacs 23.0.60 refreshes fastest…


Without vi there is only GNU Emacs
