 I just noticed that I never actually documented the original problem 
 with mcookie...
 Compiling devel/libuuid and x11/mcookie on Solaris now fails with

 mcookie fails with the same error, but NB in its own code, i.e. 
 randutil.{ch} are copied verbatim from libuuid.
 randutil.c contains an unconditional implementation of
 void random_get_bytes(void *buf, size_t nbytes)
 that conflicts with Solaris'
 extern int random_get_bytes(uint8_t *dbuf, size_t dlen);
 as long as <sys/random.h> is included. When that header is commented 
 out, other definitions are missing and compilations fails as well. I 
 guess it would take some effort to make libuuid more portable...
