popen2(), popen3():  Reversed order of bufsize and mode parameters to

class Popen3:  Factored the __init__() into a more basic initializer and
               a helper method, to allow some re-use by the Popen4 class.
               Use os.dup2() instead of os.dup() to create the proper
               file descriptors in the child process.

This closes SourceForge bug #115330 and partially closes #115353.

__file__ attributes of already-imported modules to be absolute.  This helps
robustify the interpreter against os.chdir() calls from the application.

Only remove setdefaultencoding() from sys if it exists; if this module is
run as a script (since there is a _test() function that gets run), it broke
because the script attempts to remove it again after the import of site
has already done so.  This allows the module to be run as a script again.

makepath():  New function, standardizes all pathname normalization in one
             place.

Never assume that os.sep is for the module-specific platform; use the
right separator character directly.
Fix some minor style consistency nits.

dynamically to support K&R C since we are requiring an ANSI compiler.

cStringIO does not get it right (reported as SF bug #115531).

Added test for ValueError when write() is called on a closed StringIO
object.  Commented out because cStringIO does not get it right

This *should* close SourceForge patch #115506.

Do not expose the __name__ when reporting the list of options available
for a section since that is for internal use.

This closes SourceForge bug #115357.

Additionally, define InterpolationDepthError and MAX_INTERPOLATION_DEPTH.
The exception is raised by get*() when value interpolation cannot be
completed within the defined recursion limit.  The constant is only
informative; changing it will not affect the allowed depth.

Fix the exit from get() so that None is not returned if the depth is met
or exceeded; either return the value of raise InterpolationDepthError.

fixed-length buffers without checking their length.

implementations.  Details:
  * replace 'link_shared_object()', 'link_shared_lib()', and
    'link_executable()' with 'link()', which is (roughly)
    the union of the three methods it replaces
  * in all implementation classes (UnixCCompiler, MSVCCompiler, etc.),
    ditch the old 'link_*()' methods and replace them with 'link()'
  * in the abstract base class (CCompiler), add the old 'link_*()'
    methods as wrappers around the new 'link()' (they also print
    a warning of the deprecated interface)

Also increases consistency between MSVCCompiler and BCPPCompiler,
hopefully to make it easier to factor out the mythical WindowsCCompiler
class.  Details:
  * use 'self.linker' instead of 'self.link'
  * add ability to compile resource files to BCPPCompiler
  * added (redundant?) 'object_filename()' method to BCPPCompiler
  * only generate a .def file if 'export_symbols' defined

Minor rewrites, and added the CVS ID in a comment.

caused the drive letter to cause urlopen() to think it was an unrecognized
URL scheme.  This only passes system ids to urlopen() if the file does not
exist.  It works on Windows & Unix.

It should work everywhere else as well.

In the limits.h comment, noted that INT_MAX and LONG_MAX are guaranteed
