The code will work at any time, it just blows away the old fixed
headers and makes new ones.  The user interface is that you run
$prefix/lib/gcc-lib/<target>/<version>/install-tools/mkheaders after
installation or changing headers.  I'm still unsure whether perhaps
there should be something in $prefix/bin (actually, I suspect it
really goes in $prefix/sbin).

I haven't tested it on HPUX, it would be really good to try it and see
if it works (and fix it if not...).  The testcase is to install the
compiler, save the old headers, run it, and check that you get the
same results.

Even more interesting, though, is the reason I did it.  It was necessary to
do this to have a reliable Ada bootstrap compiler.  Now, HPUX may come
with a cc, but it certainly doesn't come with GCC 3.1 Ada (which is
what GCC 3.2 Ada will require for bootstrap, I hear).
