Commit 363ae55c8 used an OCaml feature called record field punning. This broke
the build on compilers prior to OCaml 3.12.0.

This patch makes no semantic change but now uses backwards-compatible syntax.

This should be Tested-by (and maybe Reported-by). Reviewed-by implies 
that I understood what you did. I make no such claim ;-)

Other than that I don't really have comment on this patch. :-)
