I got GDB 3.2 to work with practically no effort at all, using the standard
assembler and linker that come with /ix.  I config'ed it for i386, made the
simple changes in the makefile that the config script suggests, and built it.
The only problems were that the names of some of the fields in the u. block
have changed, and there is a dependency on ioctl names that is confused.

Here are the diffs relative to distributed gdb 3.2:
