least) mutt:

  Only change the scrolling region if the window now has fewer rows.

       declaration is an obsolescent feature.

Hint: Hans sent me this diff which differs in the one from tech-kern in:
- 2-clause license
- sprinkled some consts

simonb 71a4269193 Use -nodefaultlibs instead of -nostdlib when linking libc and libgcc* 
so that we still link in the crt* start/end files.
Explicitly link libc against gcc_pic, since -nodefaultlibs undoes this.

Fixes problems where shared libraries don't get init/fini sections,
most easily noticable with pthreads programs not working.

ad 104cf0ae89 Add support for kernel preeemption to the i386 and amd64 ports. Notes: 
- I have seen one isolated panic in the x86 pmap, but otherwise i386
  seems stable with preemption enabled.

- amd64 is missing the FPU handling changes and it's not yet safe to
  enable it there.

- The usual level for kern.sched.kpreempt_pri will be 128 once enabled
  by default. For testing, setting it to 0 helps to shake out bugs.
