Wrong library.
The problem is, where are those functions defined? There are 2 uuid libraries,
one is /usr/lib/w32api/libuuid.a, but that doesn't have functions that start
with uuid. The other is /usr/lib/e2fsprogs/libuuid.a and ... bingo! that one
has the uuid_compare, etc. functions.
So change the command, and BTW libpostgres is also static, so my next guess is:
dllwrap -o uuid.dll --def uuid.def uuid.o
/usr/lib/postgresql/pgxs/src/../../src/utils/dllinit.o -L/usr/lib
-L/usr/lib/e2fsprogs -Wl,-Bstatic -lpostgres -luuid -Wl,-Bdynamic
Another hint of what may be wrong was on your first message, the "warning:
implicit declaration of function `uuid_unparse_lower'" means that the code is so
bad that they didn't even include the header.
