While rebuilding rxvt-unicode, I saw the following error during 'cygport

Preparing executables for UAC:
A little debugging showed that realpath is being invoked during
src_postinstall here:
line 978:do
# make sure that paths with '../' don't leave srcdir
case $(realpath -m ${dbgsrc}) in
${dbgsrcdir}/*) ;;
*) continue ;;
esac
srcf=${dbgsrc#${dbgsrcdir}/}
FWIW, readlink is now used in git instead of realpath, as the latter is
not available in Fedora 16 or EL6, but the result should be the same.
I see that this line is hit many times, but here is the relevant sequence:
...
realpath -m <iom_perl.xs
realpath -m -pe
realpath: unknown option -- p
Try `realpath --help' for more information.
realpath -m s/IOM_MODULE/urxvt/g,s/IOM_CLASS/urxvt/g
realpath -m |
realpath -m /usr/src/debug/rxvt-unicode-X-9.07-2/src/../libev/ev++.h
...
Although only the second of these lines triggers the error message, each
of the first four is problematic.
This looks like a bug in gcc/binutils to me; debug src paths shouldn't
include pipe line shell commands, should they?
Not AFAIK. That is very odd, but I am able to duplicate it with your
current package.
In the meantime, I think a fix like this for cygport would be appropriate:
Could you confirm that just this change fixes this:
- case $(realpath -m ${dbgsrc}) in
+ case $(readlink -m -- "${dbgsrc}") in
...although I'm not sure if this might cause a problem if a filename
actually contains a shell redirection metacharacter (and the originating
project is always careful to appropriate quote that filename).
And when was the last time you saw that?
