Thanks for that.

The way I intended to check the diff on the complex_numbers library was to

- install the library using mmc --make libcomplex_numbers.install using
  a compiler without the diff to one install prefix (ip1);

- install the library using mmc --make libcomplex_numbers.install using
  a compiler with the diff to another install prefix (ip2);

- do a recursive diff between ip1 and ip2.

The last step turns out not to work, because diff barfs on the symlinks to "..".
However, I could still do "ls -R" on both ip1 and ip2, do sed -e 's/ip2/ip1/'
on the output of the second ls -R, and compare the results. That is enough
to test the diff, since the diff itself has no way to effect the *contents* of the files
being installed; it can affect only whether and where they are installed.

Do you intend to review this diff?

Zoltan.
