I just need someone's approval.  (I should add that I'm on the Fortran commit-after-approval list, but I'm not on a general gcc list as far as I know.)

Unfortunately you didn't indicate the target you used.  Just saying 
"i386.c" isn't helpful as significant amounts of code in i386.c are 
conditionalized based on the target triplet (ie something like 
x86_64-pc-linux-gnu or i686-pc-kfreebsd-gnu.

What specific target were you trying to build?
