Re: possible gettext solution

Some more experiments, which IMO show that our understanding of how things
work is starting to converge to reality:

First I changed in gettext2 (after unpacking it in a virgin directory) 
0.17->0.18 in configure.ac. Autopoint indeed noticies this, but does not
fall for it, as it realizes that the package requires a higher version
than I have installed:

hgm@hgm-xboard:~/fboard/xboard-gettext2$ ed configure.ac
18723
/0.17
AM_GNU_GETTEXT_VERSION(0.17)
s/17/18
AM_GNU_GETTEXT_VERSION(0.18)
w
18723
q
hgm@hgm-xboard:~/fboard/xboard-gettext2$ ./autogen.sh
autopoint: *** The AM_GNU_GETTEXT_VERSION declaration in your configure.ac
              file requires the infrastructure from gettext-0.18 but this
version               is older. Please upgrade to gettext-0.18 or newer.
autopoint: *** Stop.



Then I tried the reverse, 0.17 -> 0.16. This does work. After ./autogen.sh
I cannot find any 0.17 connected to gettext anywhere; all macros now come
from 0.16. Noticeable is that the GETTEXT_MACRO_VERSION line has
completely disappeared from po/Makefile.in.in; apparently autopoint is
confident that there is no mismatch, as it provided the macros by itself,
and therefore sees no reason to let the later build steps check it:

hgm@hgm-xboard:~/fboard/xboard-gettext2$ ed configure.ac
18723
/0.18
AM_GNU_GETTEXT_VERSION(0.18)
s//0.16
AM_GNU_GETTEXT_VERSION(0.16)
w
18723
q
hgm@hgm-xboard:~/fboard/xboard-gettext2$ ./autogen.sh
