Hello,
this patch (relative to links-2.1pre17) adds rudimentary support for displaying hebrew text in the correct direction.
It does not include the changes for the build system, since I can't run the configure generated on my system from configure.in.
For compiling and linking the new code, USE_FRIBIDI needs to be defined in config.h, and -lfribidi should be on the link command line. I think adding lines like:
cf_use_bidi=no
AC_MSG_CHECKING([if you want to use bidi])
AC_ARG_ENABLE(bidi, [ --enable-bidi use bidi], cf_use_bidi=$enableval )
AC_MSG_RESULT($cf_use_bidi)
if test "$cf_use_bidi" = yes; then
AC_DEFINE(USE_FRIBIDI)
LIBS="$LIBS -lfribidi"
fito configure.in should do the trick, but I am not really sure.
