This (that it's GNU ld specific) is information that you didn't
explain first. I am probably not using GNU ld, which may explain why
I couldn't reproduce your problem.
If you want to save me the most time, please suggest the exact patch
for the documentation, using the latest version of the docs from the
CVS tree. (python.org/download/cvs.html)
To save me at least some time, write a paragraph of text and give me
at least a hint on which section of which document it should be
inserted into, and we'll figure it out from there.
