Don BURNS d7f6ab3147 Oops... experiment gon awry in makerules. This works for Solaris, but not 
Linux, evidently.  The goal was to do a dependency update on only files
that had changed, since Solaris  is so gawdawful slow at doing CC -xM

# Ok.. If you are looking hard at the following lines of gnarled code, you
# deserve an explanation. This target makes a link from the installed
# directories (Assumed to be rooted at $(TOPDIR), usually $(TOPDIR)/bin or
# $(TOPDIR)/lib) to a just-built target. Both LNSRC (Link source) and LNDEST
# (Link destination) must be defined before calling 'make __link'.
#
# The first four lines check to see that both LNSRC and LNDEST have been
# defined.
#
# The (very long) following 'if' statement reads in pseudo-code like this:
#
# if the current link is not pointing to the intended destination
# then
# announce (echo) intentions to reset link
# compute the link path by the following steps
# a) define SRCDIR as the current absolute directory
# appended by the directory of the intended source of the link
# b) define DESTDIR as the absolute path of $(TOPDIR) appended by
# the directory of the intended destination of the link
# c) define a temproary variable T to be the absolute path of
# the destination directory less the prefix of the absolute
# path of $(TOPDIR)
# e.g. /root/work/thisdir/bin/ - /root/work/thisdir/ = bin/
# d) Run a loop, truncating the path represented by T until
# 'dirname' returns '.'. On each iteration increment PFX
# (Prefix) by '../' This will define the prefix for the path
# of the link.
# e.g. If DESTDIR is lib/osgPlugins, PFX is ../../
# e) Define the link as a concatenation of PFX and the absolute
# path of the source directory less the absolute path of
# $(TOPDIR)
#
# Change directories in to the link destination directory
# run the link command
