Try:

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

I don't think you need the -L/usr/lib/w32api but maybe you do, and the chan=
ge
can also be written as -Wl,-Bstatic,-luuid,-Bdynamic .

Explanation: libuuid.a is a static library, you have to explicitly link it
otherwise the tools look only for dynamic libraries.
