I can't find any evidence of relevant external users.

bash-2.05$ find . -type f | xargs grep -c _Unwind_GetGR|grep -v :0
./gcc/ChangeLog:2
./gcc/libgcc-std.ver:1
./gcc/unwind-dw2.c:9
./gcc/unwind-libunwind.c:1
./gcc/unwind-sjlj.c:1
./gcc/unwind.h:2
./gcc/config/ia64/unwind-ia64.c:1
./gcc/doc/gccint.info-1:1
./gcc/doc/libgcc.texi:1

unwind.h has a declaration and an ia64-specific use.
unwind-libunwind.c has a different definition, but no use.

It is defined in libgcc-std.ver so other people might already be using it, right?
