Sorry about the 1.0.1 confusion.  The problem there is that the 1.0.1 gPXE 
release postdates the time that iPXE and gPXE development diverged.  You can 
work around this using:

  git remote add legacy git://git.ipxe.org/mirror/gpxe.git
  git fetch legacy --tags

That will give you a v1.0.1 tag to use as a starting point for bisection.

I'm puzzled by that.  What gcc version are you using?

Also, which git revision are you on when you get this exact error message?  
(There have been changes to hermon.c, so line 2609 doesn't mean much without 
knowing which revision we're talking about.)

Since the Hermon driver is not going to be relevant to what you're testing 
for, you can safely delete src/drivers/infiniband/hermon.c before attempting to 
build.  That will allow you to try the bisection again, this time with the 
v1.0.1 tag present and without worrying about build failures.
