Fortunately, most function replacements in gnulib are now done by
including the original system header and then only doing the
  #define func rpl_func
Only those replacements that use the old idiom of putting
  #define func rpl_func
into config.h are affected.

What's the extent of the problem? The following functions are using the
__DARWIN_ALIAS or similar macros:

dirent.h         closedir opendir __opendir2 rewinddir seekdir telldir
fnmatch.h        fnmatch
ftw.h            ftw nftw
getopt.h         getopt
pthread.h        pthread_cancel pthread_cond_init pthread_cond_timedwait
                 pthread_cond_wait pthread_join pthread_mutexattr_destroy
                 pthread_rwlock_destroy pthread_rwlock_init
                 pthread_rwlock_rdlock pthread_rwlock_tryrdlock
                 pthread_rwlock_trywrlock pthread_rwlock_wrlock
                 pthread_rwlock_unlock pthread_setcancelstate
                 pthread_setcanceltype pthread_testcancel pthread_sigmask
regex.h          regcomp
signal.h         kill killpg pthread_sigmask sigaltstack sigpause sigsuspend
                 sigwait
stdio.h          fputs freopen fwrite tempnam
stdlib.h         strtod strtof system initstate putenv realpath setenv setkey
                 unsetenv
string.h         strerror
sys/_select.h    select
sys/aio.h        aio_suspend
sys/fcntl.h      open creat fcntl
sys/mman.h       mmap mprotect msync munmap
sys/msg.h        msgctl msgrcv msgsnd
sys/poll.h       poll
sys/resource.h   getrlimit setrlimit
sys/select.h     pselect
sys/sem.h        semctl
sys/semaphore.h  sem_wait
sys/shm.h        shmctl
sys/socket.h     accept bind connect getpeername getsockname listen recv
                 recvfrom recvmsg send sendmsg sendto socketpair
sys/stat.h       chmod fchmod
sys/termios.h    tcdrain
sys/uio.h        readv writev
sys/wait.h       wait waitpid waitid
time.h           clock mktime strftime strptime nanosleep
unistd.h         close confstr encrypt fsync getopt lchown lockf nice pause
                 pread pwrite read setpgrp setregid setreuid sleep ttyname_r
                 usleep write setkey getattrlist setattrlist
wchar.h          wcsftime 

Out of these, the following are defined with #define in <config.h>:

  realpath       
  mktime
  poll           # not a problem since gnulib's poll.h does not include <poll.h>
  putenv
  regcomp        # not a problem since gnulib's regex.h does not include 
<regex.h>
  strtod

Can you please check these functions by doing

  ./gnulib-tool --test --with-tests canonicalize-lgpl mktime timegm putenv 
strtod

? Please show the "configure" output as well as all errors shown by "make -k".
