Glad to help.

I just added a cygwin-binutils-devel package with the necessary headers
and static libraries.

The only trick is you need to manually
remove /usr/i686-pc-cygwin/lib/libiberty.a so that the "correct"
libiberty.a is used instead until I have the chance to rebuild
cygwin-gcc.

I tried that at first, but it didn't work.  The problem is with
binutils:

$ i686-pc-cygwin-strings /usr/bin/i686-pc-cygwin-ld.bfd | grep w32api
SEARCH_DIR("/usr/i686-pc-cygwin/lib/w32api");

So this code isn't sysroot-safe.  PTC.

HTH,
