bison 1.50 vs binutils

[Jack Howarth]

   Has anyone built binutils cvs or 2.13.90.0.7/8 with the
newly released bison 1.50 installed? On debian ppc sid I
am seeing the following build failure which doesn't occur if
I have bison 1.35 installed...

/bin/sh ../../ld/../ylwrap "bison -y" ../../ld/ldgram.y y.tab.c ldgram.c y.tab.h ldgram.h --  -d

Any idea if this is a bug in bison or binutils?
