no :(
If that help here is the nm dump of rpcrt4:
$ nm /lib/w32api/librpcrt4.a | grep UuidCre
00000000 T _UuidCreateSequential at 4
00000000 I __imp__UuidCreateSequential at 4
00000000 T _UuidCreateNil at 4
00000000 I __imp__UuidCreateNil at 4
00000000 T _UuidCreate at 4
00000000 I __imp__UuidCreate at 4
00000000 T _I_UuidCreate at 4
00000000 I __imp__I_UuidCreate at 4
So it's definitely there.
And grep in /usr/include/w32api, I get:
rpcdce.h:RPC_STATUS RPC_ENTRY UuidCreate(UUID*);
rpcdce.h:RPC_STATUS RPC_ENTRY UuidCreateNil(UUID*);
rpcdce.h:RPC_STATUS RPC_ENTRY UuidCreateSequential(UUID*);
rpcdce2.h:RPC_STATUS RPC_ENTRY UuidCreateNil(UUID*);
rpcdcep.h:long __stdcall I_UuidCreate(GUID*);
...
