system links are not made to point to links, rather the real files. So
links installed on a system are pointing to platform specific files rather
than links that may be pointing to files of the wrong platform type.
Added a cleaner way to install demo source so that installed versions use a
simplified makedefs/makerules.
Small fix to get osgText to compile with Solaris CC. Constructor declared
with a non-const argument, but implemented with const argument.
added prefixes and suffixes to libs and plugins. ALl this to accomodate
cygwin...
Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.
the Make directory is left with four files only :
makedefs
makerules
makedirrules
instrules
These work for all platforms supported so far, which include :
Linux
Irix
Solaris
MacOSX
Cygwin
FreeBSD
