Merge patch by Stephane Fillod <fillods@users.sourceforge.net>:
* gettextsize fldigi
* add initial French translation
Minor additional changes by me (sb):
* Remove bundled intl and associated m4 macros and compiler flags
* Move new m4 macros to m4/intl
* Move gettext.h to src/include and add to src/Makefile.am
* Modify setup_nls():
* Search for message catalogs in $PWD/locale and
$FLDIGI_LOCALE_DIR/locale, in addition to LOCALEDIR
* Do not call setlocale() for LC_NUMERIC, as this can break the
configuration read/write routines when handling floating point
numbers in locales that use a comma as the decimal point
* Fix static initialisation
* Add INTL_LIBS and INTL_CFLAGS configure variables that can be used
to override AM_GNU_GETTEXT
* Update po/Makevars
* Update po files
* Remove po/Makefile.in and po/remove-potcdate.sed
Long arguments without a space (--opt=arg) now work correctly.
Also, move sound initialisation to a separate function, add an
undocumented --exit-after SECONDS argument, and update mkversions.sh
to include CXXFLAGS in the --version output.
