I think there's a mistake in the patch:

  !     @(w32srcdir=`cd "$srcdir"; pwd -W | sed -e 's,^\([[A-Za-z]]\):,/\1,' | 
${msys_to_w32}` ;        \
                                                         ^^^^^^^^^^

This should be "[A-Za-z]", i.e. only single pair of brackets.  (The
second one was necessary in an Autoconf file, to protect from
expansion by m4.)

This is on purpose, as this snippet from the top-level Makefile shows:

  # Bootstrapping does the following:
  #  * Remove files to start from a bootstrap-clean slate.
  #  * Run autogen.sh.
  #  * Rebuild Makefile, to update the build procedure itself.
  #  * Do the actual build.
  bootstrap: bootstrap-clean FRC
          cd $(srcdir) && ./autogen.sh
          $(MAKE) $(MFLAGS) MAKEFILE_NAME=force-Makefile force-Makefile
          $(MAKE) $(MFLAGS) info all
