If # this isn't the case for your libc, but it provides other aliases, # you can add e.g. "-D__mmap=_mmap -D__munmap=_munmap -D__mremap=_mremap" # to specify the alises libc provides (in this example _mmap, _munmap, # and _mremap). NB! "-D__mmap=mmap -D__munmap=munmap -D__mremap=mremap" # is not allowed as libtest overrides mmap(3), munmap(3), and mremap(3).
