Ah, I thought you were aware of the --host option for configure (it's
explained in the INSTALL file).

Here's an excerpt:

  If you want to _use_ a cross compiler, that generates code for a
  platform different from the build platform, you should specify the
  "host" platform (i.e., that on which the generated programs will
  eventually be run) with `--host=TYPE'.

Cross compiling on Cygwin for MinGC works like this:
  ./configure CC="gcc -mno-cygwin" --host=i686-pc-mingw32

and cross compiling on Linux for MinGW probably something like
  ./configure CC=/usr/something/i686-mingw/bin/gcc --host=i686-pc-mingw32

I suggest you read the documentation:
http://www.abridgegame.org/darcs/manual/bigpage.html#SECTION00220000000000000000

A checked out source tree is also a repository (and a branch, if you
will).  A darcs repository can be simply copied from one machine to
another, or you can push and pull patches to/from remote repos via ssh
using
  darcs pull user at host:path/to/repo
and
  darcs push user at host:path/to/repo

I was cross compiling on Cygwin, and the test programs built for MinGW
also seem to run under Cygwin.

Yes, I've been thinking about this.  Probably some sort of combinator
API to build regexps would be good.

Agreed.

Yeah.  It crashed when I tried to debug the TRE regression test
program :)
