I get the same error, and merging revision 197165 from trunk into my
working-directory for gcc-4_8-branch revision 198253 did not fix the error on
my system.

This error occured during one of the stages while building gcc, revision
198065, checked out from svn://gcc.gnu.org/svn/gcc/branches/gcc-4_8-branch for
MinGW32, Windows 7 Pro 64-bit SP1.
The error also occurs with revisions 198027 and 198253 -- that is, the error
has been occuring with revisions for at least these past 7 days.

The error persists after I merged revision 197165 from trunk into my
working-directory for gcc-4_8-branch revision 198253.
