Explain what to do in case of missing shared libraries. Remove mentioning

of egcs. Fixes #635929. Backported to 2.2.3.

 If you get failures in test_long, or sys.maxint gets set to -1, you
 are probably experiencing compiler bugs, usually related to

 From Python 2.0 onward, all Python C code is ANSI C.  Compiling using
 old K&R-C-only compilers is no longer possible.  ANSI C compilers are
