another bootstrap failure on sparc-sun-solaris28 in cp/xref.o

[lucier@math.purdue.edu]

I'm getting a lot of strange bootstrap failures on sparc today.  This one has the
message:

../../gcc/cp/xref.c: In function `GNU_xref_member':
../../gcc/cp/xref.c:599: parse error before "value"
../../gcc/cp/xref.c:602: parse error before "confg"

This is building stage2 with the stage1 compiler with make -j 12 bootstrap after
a generic configure.

The code in question is indeed nonsense, see lines 9125-9126 of

http://www.math.purdue.edu/~lucier/xref.i

It has something to do with the macro exansion of 

  if (TREE_CODE (fld) == FUNCTION_DECL && DECL_CONST_MEMFUNC_P(fld))
    confg = 1;
