Procedure for cherry-picking

[Ken Brown]

I've been away from Cygwin development for a while, and I've forgotten 
(or never knew) the conventional way of cherry-picking a commit from the 
main branch to the cygwin-3_5 branch.  Here's the context:

Last February it was discovered that a build of Cygwin with -Og failed 
because of some gcc warnings that were treated as errors.  Corinna fixed 
this on the main branch in commit e99dbf6c25c3.  I just tried to build 
the cygwin-3_5 branch without optimization and ran into the same 
problem.  So Corinna's fix needs to be applied to that branch.  My 
instinct is that I should checkout the branch and do

   git cherry-pick e99dbf6c25c3

and then amend the commit to add a note that it was cherry-picked.

The weird thing about this is that we would then have a commit dated Feb 
14 on top of a commit dated Sep 1.  Is that a problem?  If so, how 
should I handle this?

Thanks.
