Re: [Simulavr-devel] binutils2.19 bug [was:Getting Started with simulavrxx]

[Joel Sherrill]

Thank you!!

I can now get far enough to see the TCL GUI run.  YEAH!!

This is a summary of what I had to do:

+ move gui.tcl.in to gui.tcl (does it have to be a .in? what is
  substituted?)
+ copy check.tcl.in to check.tcl and fix the substitutions by hand.
+ copy anacomp/Makefile.am to anacomp/Makefile and fix it by hand.

I can submit a PR and patch if you want me to.

Now to figure out how to actually use the simulator.  I will
try to submit documentation improvements as I learn.  I know
from experience that it is hard to document something you know
inside and out.

I filed a few PRs with patches so far. 

Thanks again.
