Chet --

This patch begins adding support for MinGW to readline.  There is one 
other patche required, which is *much* smaller, but somewhat more 
complex; this patch is the large, mechanical patch.  In general, this 
patch checks for the availability of more things in autoconf, and then 
disables uses of those things when they are not present.  There are no 
actual changes to the code itself, just additional conditionals, with 
the exception that a call to "kill" is turned into a call to the POSIX 
"raise", which, unlike "kill", is also available on Windows.

The GDB maintainers have asked that I post this patch both to the GDB 
patches list, and also to the readline patches list.  The hope is that 
you (Chet) will accept this patch -- or some variant thereof -- into the 
upstream readline so that there will not be divergence between GDB's 
readline and the official version.

The overall purpose of this work is to get the FSF version of GDB 
working on MinGW.  The necessary patches are already in GDB itself; all 
that remains is the readline bits.

Thanks in advance for your consideration.
