In the applications (and that is the major code block) practically
everything, as everything has at least some UNO wrapper -- and UNO is
also used a lot internally.

Some sal_* => "int" conversion that works on all current platforms does
not have to on the next one coming around.

I think most code now uses sal_* as of now and less code uses the
standard ones. For example, searching for this stuff roughly a la
find clone -name "*.cxx"|xargs grep "unsigned int"|wc -l
in clone (excluding libs-extern):

                               sal_uInt32    unsigned int
clone without external              24005            1246
  hxx                                7560             256
  cxx                               16445             999

Thus my conclusion.

Agreed. Changing stuff there will just create lots of useless merge
conflicts. And if we see Oracle doing something stupid with sal_uLong,
we should do our better solution after _merging_ that. The worst
situtaton however is: they walk on to greener pastures because
priorities changed this week and sal_uLong keeps hanging around.

Best Regards,
