  I would like to update include/longlong.h to pick up the latest changes
from GCC and keep this file in sync.  I think changes to keep files 
in sync are considered pre-approved so if I don't hear any objections
I will go ahead.  The changes in GCC that are not yet in the binutils
tree are:

2014-05-01  Steve Ellcey  <sellcey@mips.com>

	* include/longlong.h: Use 'defined()' to check __mips16.

2014-04-30  Richard Sandiford  <rdsandiford@googlemail.com>

	* longlong.h (__i386__): Remove W_TYPE_SIZE==64 handling.

2014-04-22  Yufeng Zhang  <yufeng.zhang@arm.com>

	* longlong.h: Merge from glibc.

Yes, these resyncs should be considered pre-approved.

Thanks for doing this,
