[Caleb C. <cal...@gm...>]

So I found all the libs in question in my /lib directory.  I updated my
Makefile.cfg to use:

...
*# cygwin**
**# these must point to your sh-elf bfd, not the system one**
**BFDLIB = -L/usr/local/dc/i686-pc-cygwin/sh-elf/lib -lbfd -L/lib -liberty
-lintl -lz**
**BFDINCLUDE = /usr/local/dc/i686-pc-cygwin/sh-elf/include**
*
*...*
*
*
Ran a "make clean" just to be sure and then another "make" and here is what
I'm getting:

*Caleb@Caleb-TouchPC/cygdrive/c/Users/Caleb/Dreamcast/Development/dcload-ip-1.0.4

It doesn't look like the host-tool is even using the BFDLIBs so maybe
something else is wrong?*
