Hi folks, [Please Reply All to CC me as ISP blocking Cygwin lists]
I previously submitted a patch upstream to add DESTDIR when creating
package symlinks so cygport builds work without patches.
Now another downstream is disputing that, requesting the patch be
reverted, saying that symlink targets are contents and should always be
from the non-DESTDIR native source as per GNU "rules" in the autobook.
A link to this discussion would be useful.
We agreed to request other more experienced opinions on this issue from
our support groups and report back.
I am asking the perhaps more experienced professional maintainers to
provide their considered opinion on this issue, demonstrated by the
reversion patch below.
The link's target must not include $(DESTDIR), otherwise this ends up
included in the shipped link. Linking the theoretical target gives the
correct result.

This patch looks correct.
Think of it this way: --prefix etc. configures the location of the
installed files, DESTDIR selects a temporary staging directory that the
files are placed into (e.g. before packaging)
So, targets of symlinks which are absolute paths should not contain DESTDIR.
