 Description:
 This directory contains the source code of ICU 4.6 for C/C++
 
 1. It was obtained with the following:
 
     $ svn export --native-eol LF http://source.icu-project.org/repos/icu/icu/tags/release-4-6 icu46
 
-2. Platform header files for Linux, FreeBSD, OpenBSD, Android and Mac OS X:
+2. Platform header files for Linux, FreeBSD, OpenBSD, Android, Mac OS X, and QNX:
 
    - Apply platform.patch in patches directory. : It applies the upstream
      patch to platform.h.in (see http://bugs.icu-project.org/trac/ticket/8248)
      and change source/common/unicode/ptypes.h to refer to plinux.h and
      pmac.h generated below.
 
    - 'runConfigureICU Linux', 'runConfigureICU FreeBSD', and
      'runConfigureICU MacOSX' are run to generate
      source/common/unicode/platform.h.
 
    - 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.
+
    - For NaCl (icu_nacl.gypi), the pnacl.h was generated by copying plinux.h to
      pnacl.h and applying the patches/pnacl.h.patch.
 
    - Apply the CL at https://codereview.chromium.org/15973007/ to plinux.h

 27. Change export of U_ICUDATA_ENTRY_POINT from U_IMPORT to U_EXPORT.
     - patches/declspec.patch
 
 28. Add support for QNX Neutrino.
     -  patches/platform.qnx.patch:
-       Add source/common/unicode/pqnx.h.

     -  patches/si_value.undef.patch:
        Work around an all-lowercase macro defined in <signal.h>.
