Very Computer

I am running NetBSD 1.1 for sparc at home.  I wanted xxgdb, so I fetched
the 1.12 sources from ftp.x.org.  Here are the changes I made to get
it to compile and work under NetBSD 1.1/sparc.

The problems amount to xxgdb sources believing that if BSD is #defined,
it has to use "struct sgttyb" stuff.  Not so, for NetBSD - it uses
struct termios stuff.  It's also missing the TCGETA/TCSETA ioctls,
too.

There was also some weirdness with the scrolling of the gdb input
window.  It wouldn't scroll until a whole lot of gdb input/output text
had scrolled beyond the bottom of the window.  I just un-ifdef'ed
someone else's hack to correct this.
