bug#7557: 23.1; Flymake fails when used in conjunction with Tramp

[Kevin Montag]

When opening a remote PHP file using Tramp over SSH, a message box 
appears with the text "Flymake: Configuration error has occured while 
running (php -f index_flymake.php -l). Flymake will be switched OFF", 
and Flymake is not used.  If a copy of the file is opened locally, no 
message appears and Flymake works as expected.

Changing 'start-process' to 'start-file-process' in 
'flymake-start-syntax-check-process' of flymake.el (as suggested in 
http://groups.google.com/group/gnu.emacs.help/browse_thread/thread/dda14275ce2b8b02/d58b601f2b3be223) 
partially fixes the problem.  With this change, Flymake performs syntax 
checks on remote files without an error message - however, the buffer is 
marked as modified each time such a check is performed.
