TMPDIR -- Environmental Variable

Directory that holds temporary files

The command  cc reads  the environmental variable  TMPDIR to see  where you
want  it  to write  its  temporary  files.  You  can  speed compilation  by
building a RAM disk and pointing TMPDIR to point at it.

For example, if  you have created a RAM disk  and mounted it as /z, then by
embedding the instruction

    export TMPDIR=/z/tmp

in your  .profile, you can ensure  that cc will write  all of its temporary
files onto the RAM disk.
