./configure uses pkg-config to test for gnutls, so you need to have
pkg-config as well as the gnutls.pc file in the pkg-config
PKG_CONFIG_PATH. Try running

   pkg-config --debug gnutls

Using --with-gnutls=no works for me, is it possible you have some
extra whitespace after one of the backslashes?

Hmm, doesn't happen for me, but you can try enlarging DUMPED_HEAP_SIZE
in src/w32heap.c
