Ok - much better. Thank you very much. This time bombed out with dllinit.o not
found, so changed that path:

dllwrap -o uuid.dll --def uuid.def uuid.o
  /usr/lib/postgresql/pgxs/src/utils/dllinit.o -L/usr/lib
  -L/usr/lib/e2fsprogs -Wl,-Bstatic -lpostgres -luuid -Wl,-Bdynamic

and I now only get:

uuid.o:uuid.c:(.text+0x174): undefined reference to `_uuid_unparse_lower'
uuid.o:uuid.c:(.text+0x2fd): undefined reference to `_uuid_unparse_lower'
collect2: ld returned 1 exit status
dllwrap: gcc exited with status 1

Their uuid.c does include <uuid/uuid.h>, but /usr/include/uuid/uuid.h doesn't
include the uuid_unparse_lower function; nor does

strings /usr/lib/e2fsprogs/libuuid.a | grep lower

return anything.

Latest Cygwin version of e2fsprogs is 1.35-3, but the latest release on
Sourceforge is 1.40.2. Downloaded that release, checked lib/uuid.h and the new
uuid_unparse_lower function is there. Tried building the whole packge,
but it doesn't build out of the box (error at the bottom if anyone's
interested) - however it does
build libuuid. So, updated /usr/include/uuid/* and
/usr/lib/e2fsprogs/libuuid.a,
and now it builds and works perfectly.

Thanks very much for your help,

Ant.
