I had to fix some source files because of macro redefinitions and such stuff.

Small modules like basic have a great win, too:

make basic.clean && time make basic:

                with    w/o
                 pch    pch
accessibility    23s  1m59s
basctl           30s  1m42s
basic            56s  1m35s
comphelper       23s    51s
editeng          48s  2m04s
forms            40s  1m40s
unotools         19s    38s
sd             3m37s  4m33s
