Apparently I haven't made myself clear.  I see no reason to
suppose that gcc has been patched by anyone outside the gcc
developer group.  It seems more likely that they put in a
capability for enabling these transformations, triggered by a
setting in library header files.  The people who put together the
Ubuntu distribution simply enabled the setting in the library
headers;  they didn't any changes to gcc itself.  So gcc should
have a way of turning off that outside interference, since they
are the ones who enabled it in the first place.

Disclaimer:  I have no direct knowledge of who made what changes
to gcc source.  I am simply making an educated guess based on
whatever miscellaneous evidence has been discovered during my
various perusings.
