When building 5.003_91, I noticed that Configure leaves a load of files lying
around in /tmp, for example exp21743c, etc. These appear to contain lists of
symbols. A bit of digging reveals that the offender is the perl_exp.SH
script. This contains a bit of code of the form
(
trap "rm -f ...." 0
...
)
I guess that when the sub-shell invoked by the ( ... ) construct exits, the
trap 0 should be taken, and the files removed. Unfortunately, I have noticed
that on at least 2 systems (UnixWare & Unisys SVR4) this doesn't happen. The
following patch fixes it.
