Subject: 23.3.50; flymake handles read-only directories badly

If I open a system include file, and have flymake-mode in my
c-mode-hook, I get:

Note: file is write protected
flymake-save-buffer-in-file: Opening output file: permission denied, /usr/include/regex_flymake.h

and (the actual bug) the buffer displayed is not regex.h

Maybe flymake should use temporary directories under /tmp to create its
temporary copies of files in non-user-writable directories?
