This appears to be in the context of updating the port of VIM?

I previously replied to someone not that long ago to look at the vms 
specific source for Bash 4.2.39 at the GNV sourceforge cvs repository.

The source is also available for extraction from the Bash 4.2.39 PCSI 
kits at ftp.encompasserve.org/gnv/....

In that source is the hacks needed to make a wrapper for select() and 
poll() that work on pipes, terminals, and X11 file descriptors.
That hack is also in the GLIB port source that is also in a PCSI kits.

It also has the fixes needed to get the correct terminal geometry on VIM.

When I discovered that it was broken on the older Bash, a internet 
search showed the source code to VIM was using the same code that did 
not work.

The code in Bash 4.2.39 works and can be put into VIM.
