Perhaps that's not what you meant to ask? By general, do you mean 
generic (definitely not including -msse4)?

http://gcc.gnu.org/onlinedocs/gcc-4.4.6/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options

-msse4.1 and -msse4.2 are listed there.

  -mtune=barcelona , which you might use for Core I7 (with or without 
-msse4), if you don't want to use a current gfortran, is listed there.
