This is not really a bug report.

I extracted the Emacs 19.27 source tree on an NFS partition. When the
installation process got as far as dumping itself (ie. temacs), it
core dumped since Irix does not support mmap() over NFS. This really
shouldn't have come as a surprise to me, but I spent quite some time
before I figured out the reason for the core dump :-)

I re-extracted the sources in /tmp, and then it compiled without a
hitch.

Possible solutions:
    temacs can be modified to dump to /tmp, then copy it from there.
    Perhaps temacs could sense the file system type and act
    accordingly (I can contribute such code for (at least) Irix if
    this is wanted)
or 
    put a note about this problem in etc/MACHINES

(I think Linux is another OS which doesn't support writeable mmap over
NFS, which is why I suggest the first solution.)
