Hi,

Please backport the change from 
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg00713.html to gcc 4.9.

2014-12-30  Lynn Boger <laboger@linux.vnet.ibm.com>

     * libgo/mksysinfo.sh:  Add the same compiler flags used by 
configure to detect whether off64_t is present
        when generating the go structures for C types.  Otherwise the go 
type for off64_t might not be
        generated.

The patch you attached is not a backport of the change to trunk.

This one should not be backported.  It was submitted but not added 
upstream.  Sorry for the confusion.
