A patch from Pascal Stumpf using external jpeg broke linux builds,
since libjpeg needs to be linked in when using a remote jpeg lib.
So, in lnxLib.tmpl, define SharedDtHelpReqs so -ljpeg is used. Also,
in DtHelp/Imakefile, use proper Arch defines so external jpeg libs are
only used on linux, fbsd, and obsd systems.
It is amazing what mayhem can be caused by a bad define :)
The reason most of the CDE programs were not actually using their
localized catalogs was because their use was being disabled by this
line.
Certain programs like dtwm and dthelp/libDtHelp did their own
localization handling and did not use the results of this define.
This is why they worked properly, and most everything else did not :)
Added proper SharedDtSvcReqs in lnxLib.tmpl and CplusplusLibC in
linux.cf. This allows the libstdc++ dependancy to be properly
declared for libDtSvc so that it is not neccessary to hardcode 'CCLINK
= g++' in the Imakefiles of programs linking angainst libDtSvc.
