A few different questions. Long.

Unless you're seeing something different than I, the configure script
is not actually failing.  It's issuing a warning and defaulting to
using "ld" from your PATH which should be ok if you've set up everything
correctly.

Yup.

As has been mentioned many many many times on this mailing list, the
*.core files that cygwin creates are simple ascii files.  They are
intended for human consumption not gdb.  I've changed the name of these
files to something.stackdump in recent snapshots to work around this
problem.

You can (tediously) decode the addresses in the file via addr2line.

If you run your program under gdb it will operate just like under UNIX
and stop at the offending instruction which caused the core dump.

set CYGWIN=ntea

will provide you with more permissions.  Watch out, though, if you use
this on a FAT partition it will create a large file which is not easily
deletable.
