Steps to reproduce the problem

  1. Install the official Cygwin-based OCaml installer;
  2. Install Odb by downloading the latest odb.ml, adding appropriate lines to findlib.conf, ld.conf and creating the ~/.odb/lib directory;
  3. Run the Cygwin shell;
  4. Install type_conf with ocaml odb.ml type_conv (should succeed).

Root of evil

The build system should have called not cpp but i686-w64-mingw32-cpp. That is how a properly packaged C library would compile when configured with --host=i686-w64-mingw32.

This one definitely needs forwarding to the sexplib maintainers. The call to cpp even has -I/mnt/local/sda1/ysulsky/src/misc/public/ocaml-core.bak/base/sexplib/syntax hard-coded in it. I'll send them a link to this excellent report.
