Netscape for linux has many bugs arround i18n, because Motif
which statically is linked to netscape has many bugs arround i18n 
originally. So, in order to fix netscape's i18n bugs, we have to
fix the Motif's bugs and link the fixed Motif to netscape. 

(mozillafix and ns-bogus-locale is just an only temporary kludge, 
 so doesn't provide absolute solution.)

However, Motif was not an opensource and I heard (that is to say
I don't examine) that OpenMotif (http://www.opengroup.org/openmotif/)
could not link the netscape because of version incompatibility 
(OpenMotif is 2.1, Netscape's linking one is 1.2).

So we should use lesstif, however, which also has many bugs 
around i18n. But, Mr. Funada (fun) has fixed these bugs and provides 
RPM packages for Kondara MNU/Linux (http://www.kondara.org/) which 
is a leading distribution in Japan and derived from RedHat. 

How to use netscape on lesstif:
(assume on RedHat or derivative distribution from RedHat)

1. compile and install lesstif with i18n patch
   Currently, compatible version of lesstif to fun's i18n patch
   is not found in lesstif's site (ftp://ftp.hungry.com/), so 
   we can get only older version of lesstif and fun's patch 
   from Kondara-Zoo. 

   binary packages (don't check it except on Kondara):
      ftp://rufus.w3.org/linux/Kondara/Kondara-Zoo-1.2/i586/lesstif-0.90.9-1k1.i586.rpm

   source packages:
      ftp://rufus.w3.org/linux/Kondara/Kondara-Zoo-1.2/SOURCES/lesstif-0.90.9.tar.gz
      ftp://rufus.w3.org/linux/Kondara/Kondara-Zoo-1.2/SRPMS/lesstif-0.90.9-1k1.nosrc.rpm
   or
      ftp://rufus.w3.org/linux/Kondara/Jirai-Zoo/SOURCES/lesstif-0.91.0.tar.gz
      http://cgi.shikoku.ne.jp/~fun/srpms/lesstif-0.91.0-1k2.nosrc.rpm

   (currently, Kondara have been restructuring own distribution,
    so if you don't find them, I put them in my webpage.)

   Compile and install it, like:
      su root
      cp lesstif-0.91.0.tar.gz /usr/src/redhat/SOURCES
      rpm -ivh lesstif-0.91.0-1k2.nosrc.rpm
      cd /usr/src/redhat/SPEC/
      rpm -bb lesstif.spec
      rpm -ivh ../RPMS/i386/lesstif*

   UPDATE: lesstif-0.92.6 and i18n patch for 0.92.6 are available.
     ftp://ftp.hungry.com/pub/hungry/lesstif/srcdist/lesstif-0.92.6.tar.bz2
     http://cgi.shikoku.ne.jp/~fun/srpms/lesstif-0.92.6-i18n.patch
     http://cgi.shikoku.ne.jp/~fun/srpms/lesstif-0.92.6-0k.nosrc.rpm

2. install dynamic linked version of netscape
   Download original netscape archive from netscape's site:
      ftp://ftp.netscape.com/pub/communicator/english/4.76/unix/supported/linux22/complete_install/communicator-v476-us.x86-unknown-linux2.2.tar.gz
   and extract it, execute the 'ns-install' to install into some 
   directory. 
      
   In order to run a plugin correctly, backup original libnullplugin.so 
   in installed_directory/plugins, and replace the libnullplugin.so 
   with libnullplugin-lezilla5.so:
      http://cgi.shikoku.ne.jp/~fun/srpms/libnullplugin-lezilla5.so

   NOTES:
   RealPlayer plugin outputs 'rpnp.so: undefined symbol: __pure_virtual'
   doesn't work (flash plugin does work fine).  

   Temporary solution:
     I'm not familar with the internal structure, so I'm not sure that 
     it is right solution: 
       1. to extract libgcc.a in the gcc's directory like
         ar x /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/libgcc.a
       2. link _pure.o as shared library with export symbols like
          gcc -o libpure.so -fPIC -shared -Wl,-export-dynamic,-soname,libpure.so.0 _pure.o
       3. copy libpure.so to a some directory like
          cp libpure.so /usr/lib/netscape
       4. preload when executing netscape-dynMotif like
          env LD_PRELOAD=/usr/lib/netscape/libpure.so netscape-dynMotif

       prelinked version is here (which is not tested except Redhat):
         http://www.geocities.com/SiliconValley/Grid/8453/libpure.so.gz

   binary package and source packages are found in there,
      ftp://rufus.w3.org/linux/Kondara/Kondara-1.2/i586/Kondara/RPMS/netscape-common-4.73-0k2.i586.rpm
      ftp://rufus.w3.org/linux/Kondara/Kondara-Zoo-1.2/i586/lezilla-4.73-1k3.i586.rpm
      ftp://rufus.w3.org/linux/Kondara/Kondara-1.2/SRPMS/SOURCES/communicator-v473-export.x86-unknown-linux2.2.tar.gz
      ftp://rufus.w3.org/linux/Kondara/Kondara-1.2/SRPMS/SOURCES/navigator-v473-export.x86-unknown-linux2.2.tar.gz
      ftp://rufus.w3.org/linux/Kondara/Kondara-1.2/SRPMS/SRPMS/netscape-4.73-0k2.nosrc.rpm
      ftp://rufus.w3.org/linux/Kondara/Kondara-Zoo-1.2/SRPMS/lezilla-4.73-1k3.nosrc.rpm
   however, several security holes are found in above version, so 
   deal them carefully.
      
3. run dynamic linked version of netscape
   Simply go to the installed directory and run './netscape-dynMotif'
   instead of 'netscape'. If you use RPM packages, run 
   '/usr/bin/lezilla'.

   NOTES: 
   If you hit a crash sometimes when opening File Selection Box, 
   change '*nsMotifFSBHacks: True' to '*nsMotifFSBHacks: False'
   or reverse in Netscape's Resource file (normally found in 
   /usr/X11R6/lib/X11/app-defaults/Netscape)

NOTES: 
Japanase program is almost run in EUC-JP charset environment
in UNIX and SJIS charset environment in Windows and MacOS, so I 
check netscape in only EUC-JP environment. I heard KS C 5601 (EUC-KR?) 
is rather similar to EUC-JP and Big-5 charset is rather similar 
to SJIS and GB charset is rather similar to EUC-JP. If netscape on 
lesstif doesn't run correctly on Big-5 environment, test it on GB 
environment, please (Reported both of them work well. Thanks to 
Mr. Chih-Wei Huang).

KNOWN BUGS:
A current lesstif doesn't support X11R6's XIM extension 
(XRegisterIMInstantiateCallback and XNDestroyCallback), so if you 
kill XIM server when running Netscape, Netscape always crash.
