deduce locations of latest translations.
Use this function to grab both bison and bison-runtime .po files.
Don't bother priming the pump for the runtime-po domain any more,
as it's now translated better than bison is.

(using GNU make) does not worry about configuring gzip. This also
works around a bug reported independently by Keith Thompson and by
Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
stderr rather than stdout, messing up the build logs.
(b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
'const YYSTYPE', and similarly for YYLTYPE. This fixes one
of the bugs reported today by Derek M Jones in
<http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.

when two actions appeared in succession, the second one was
