 It looks like it's always been a bug, but until now there hasn't been
 an OS that defined mempcpy (not memcpy) and not also __mempcpy, so we
 just didn't trip over it.

 Yes its the same bug...
 
 Well it depend on how you define regression. It seems like this is a 
 Cygwin regression and not a gcc one, because it *did* work on the 
 gcc-3.3-branch at 20030315, and now it dont (using that date's 
 snapshot). The same applies to the 3.2.x branches.
 
 But my point is, that if this is caused by a Cygwin thing, what approach 
 should we take to fix it? Fix Cygwin or fix gcc?

 I ran into the same problem here (PR10198):
 http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=10198
 
 So I don't think it's a regression.  It seems to be present on all of the 
 3.2.x branches, so I'm guessing it's a Cygwin problem.  I worked around it 
 similarly by just not using __memcpy(), and instead memcpy() in the #else 
 branch.
