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

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
available for all modern systems, either in the form of updated

Linux: A problem with threads and fork() was tracked down to a bug in
the pthreads code in glibc version 2.0.5; glibc version 2.0.7
solves the problem. This causes the popen2 test to fail;
