Not that I know about, the problem is that the file is opened and the system (Win)
doesn't allow deleting or overwriting of files that are in use (opened).

Opening and writing are the same as in Linux, but deleting/overwriting differs.

I can build a new perl version if needed and I can help if you build it yourself.

Well, there may be changes in the relevant parts, but basically it should
be the same.

In the cygwin sources there is the build script included, try to
build without the modules at first.
Also try to use the Configure flag -Dmksymlinks, so you don't
need to build in the source directory.
I use this kind of script to build bleadperl:

#!/bin/sh
set -e
set -x
rm -rf ./buildperl
mkdir -p -m 777 ./buildperl
cp -p ./Policy.sh ./buildperl/Policy.sh

# configure perl
cd ./buildperl
sh /ftproot/pub/mirror/bleadperl/Configure -de \
                   -Dmksymlinks \
                   -Dusemultiplicity \
                   2>&1 | tee log.configure

make 2>&1 | tee log.make

cp -p /bin/cygwin1.dll ./t/
chmod 777 ./t/cygwin1.dll

# make test
make test 2>&1 | tee log.make-test

# make harness
(cd t;./perl harness) 2>&1 | tee ./log.harness

rm -v ./t/cygwin1.dll

# install later (does 'make install' works now?)
# make install.perl install.man 2>&1 | tee log.install

# If your patch works ok, the .bak below isn't needed;)
perl -i.bak -p -e 's#for trythis in .*#for trythis in /usr/bin/perl /bin/perl#;' \
       -e 's#[^ ]*perlld#/usr/bin/perlld#' /usr/bin/ld2
echo 'check /bin/ld2'
