[issue6114] distutils build_ext path comparison only based on strings

[Sven Rebhan]

Sven Rebhan  added the comment:

Of course there is a secret distutils comunity using git! ;-) The three ppl 
mentioned there found and fixed the problem, that's why.

But back to the issue: Can we use a switch or wrapper function to change the 
test method for this path dependent on the OS? I'm asking because in windows 
there might be no symlink either and everything just works(tm).

[issue6114] distutils build_ext path comparison only based on strings

[Sven Rebhan]

New submission from Sven Rebhan :

If python is installed into a symlink'ed directory, the variables
"sys.exec_prefix" and "sys.executable" can contain different paths.
Therefore, the respective test in build_ext.py fails (line 202)
and a wrong library search directory (-L.) is set.

The attached patch fixes this issue, by using os.path.samefile() instead
of the string comparison to see whether two files are identical
irrespective of their paths.
