Gerrit,
Thanks for the suggestion but I wanted to avoid moving to a new
version of Perl since the production application that I'm working
on is 5.8.0. I noticed that after compiling 5.8.0 from the source
distribution (5.8.0-5) perldoc fails with an error message about
not being able to create a temporary file:

Checking the log.test file created by the build.sh script, I noticed
that the test of tempfile failed:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
lib/File/Temp/t/tempfile.............Error in tempfile() using
/tmp/XXXXXXXXXX.t xt: Could not create temp file /tmp/yvTTCjl9aJ.txt:
at ../lib/File/Temp/t/tempfile.t line 48
FAILED at test 2
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
But, then I noticed this in the log:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Failed 46 test scripts out of 659, 93.02% okay.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Despite this, the build.sh script goes ahead and installs the
recompiled Perl 5.8.0. Is this reasonable behavior?
It appears that Cygwin doesn't support the creation and opening
of a temporary file to avoid a race condition as intended by the
File::Temp::tempfile function. The perldoc seems to indicate
that the use of the File::Temp:tmpnam function would probably
be a better choice under for perldoc under Cygwin since apparently
Cygwin can't handle the file semantics as described in the perldoc
for File::Temp::tempfile.
Thanks,
Russ
