-   - On OpenBSD, source/common/unicode/platform.h is being generated
-     by the icu4c port in the ports directory and not by runConfigureICU.
-     In case the file has to be updated you can do:
-     cd /home/ports/textproc/icu4c && make configure
 
-   - Rename it to 'plinux.h', 'pfreebsd.h', 'popenbsd.h' and 'pmac.h'

-   - Apply patches/pmach.h.patch on Mac to pmac.h
-
-   - On Android, the pandroid.h was generated by copying plinux.h to
-     pandroid.h and applying the patches/pandroid.h.patch.

-   - For QNX, the pqnx.h was generated by copying plinux.h to
-     pqnx.h and applying the patches/platform.qnx.patch.
