When you wrote this:
CCS=`perl -e 'local $/=undef; open FILE, $ENV{'PATCHTMP'};...
which one of the following did you mean to feed Perl?
(1) open FILE, $ENV{'PATCHTMP'};
(2) open FILE, $ENV{PATCHTMP};
The patch text makes it look as if you wanted to do (1), but what is
fed to perl is (2), as Johannes points out.
Saying:
CCS=`perl -e 'local $/=undef; open FILE, $ENV{PATCHTMP};...
would have been more natural if you really meant to do (2), don't
you think? So what you wrote is at least misleading.
But I think I agree with Johannes's rewrite of the loop, so this may
be a moot point.
