  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.
