This trick is needed to enable -Dlibperl=cygperl5_10.dll
for building XS extensions without going through the importlib.
This way the dll can be named as you wish, to enable multiple versions
and features (threaded/non-threaded, debug) of perl together.

I see.
/usr/lib/perl5/5.10/i686-cygwin/CORE is wrong in PATH.
It only belongs to LIBPATH.
There are no binaries there to pickup.

No, please remove /usr/lib/perl5/5.10/i686-cygwin/CORE from your path
in your Makefile. The symlink is needed to build perl extensions.

windows needs the dll to be in the path which is /usr/bin.
ld needs to link against the dll and expects it in
/usr/lib/perl5/5.10/i686-cygwin/CORE, hence the symlink, because ld
understands the symlink, windows not.
