Details:

Hi,

When I built gettext 0.19.8.1 on MinGW, the DLL name of libintl
was libintl-8.dll.
But now I build gettext 0.20, the name becomes libintl-7.dll.
The interface number was decremented from 8 to 7, so gettext 0.20
is not binary compatible with 0.19.8.1 or before.
(I think that the same thing occurs in linux, etc.)

If gettext 0.20's API is compatible with 0.19, the file name
should keep libintl-8.dll. Otherwise it should be libintl-9.dll,
not libintl-7.dll.

This is caused by the -version-info option for Libtool set in
gettext-tools/intl/Makefile.
In 0.19.8.1, it was -version-info 9:5:1, but in 0.20, it is
changed to -version-info 9:6:2.
To keep the binary compatibility, -version-info should be
9:6:1, 10:0:2 or something. If the AGE is incremented, the
CURRENT should be also incremented.
