If you get failures in test_long, or sys.maxint gets set to -1, you
are probably experiencing compiler bugs, usually related to
optimization. This is a common problem with some versions of gcc and
egcs, and some vendor-supplied compilers, which can sometimes be
worked around by turning off optimization. Consider switching to
stable versions (gcc 2.7.2.3, egcs 1.1.2, or contact your vendor.)

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
compilers from the vendor, or one of the free compilers (gcc, egcs).

When the dynamic loader complains about errors finding shared
libraries, such as
ld.so.1: ./python: fatal: libstdc++.so.5: open failed:
No such file or directory
you need to first make sure that the library is available on
your system. Then, you need to instruct the dynamic loader how
to find it. You can chose any of the following strategies:
1. When compiling Python, set LD_RUN_PATH to the directories
containing missing libraries.
2. When running Python, set LD_LIBRARY_PATH to these directories.
3. Use crle(8) to extend the search path of the loader.
4. Modify the installed GCC specs file, adding -R options into the
*link: section.
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;
