   3  * Namespace all expat exported symbols to avoid dynamic loading symbol
   4  * collisions when embedding Python.
   5  *
   6  * The Problem:
   7  * - you embed Python in some app
   8  * - the app dynamically loads libexpat of version X
   9  * - the embedded Python imports pyexpat (which was built against
  10  *   libexpat version X+n)
  11  * --> pyexpat gets the expat symbols from the already loaded and *older*
  12  *     libexpat: crash (Specifically the crash we observed was in
  13  *     getting an old XML_ErrorString (from xmlparse.c) and then calling
  14  *     it with newer values in the XML_Error enum:
  15  *
  16  *       // pyexpat.c, line 1970
  17  *       ...
  18  *       // Added in Expat 1.95.7.
  19  *       MYCONST(XML_ERROR_UNBOUND_PREFIX);
  20  *       ...
  21  *
  22  *
  23  * The Solution:
  24  * Prefix all a exported symbols with "PyExpat_". This is similar to
  25  * what Mozilla does for some common libs:
  26  * http://lxr.mozilla.org/seamonkey/source/modules/libimg/png/mozpngconf.h#115
  27  *
  28  * The list of relevant exported symbols can be had with this command:
  29  *
  30        nm pyexpat.so \
  31            | grep -v " [a-zBUA] " \
  32            | grep -v "_fini\|_init\|initpyexpat"
  33  *
  34  * If any of those symbols are NOT prefixed with "PyExpat_" then
  35  * a #define should be added for it here.
