Re: [PATCH] Merge of readline 4.3 to mainline

[Michael Elizabeth Chastain <mec@shout.net>]

Heh.  I figured out what's special about my system.

I build the whole toolchain from scratch, starting with gnu make, then
binutils, then a baseline version of gcc.  Then I use the baseline tools
to build everything else, including all the binutils, gcc's, and gdb's
that I test with.  Then I run all the tests.

The idea of the baseline is to make a test bed that can bootstrap on
systems without the gnu toolchain, like Solaris.

My baseline compiler is gcc 2.95.3, because it's simple and fast.

When I build gdb with /bin/cc, or when I use gcc 3.2.1 + binutils 2.13.1,
the strange behavior in readline does not happen and my gdb.log looks
normal and good.

So it's some interaction with building gdb with gcc 2.95.3 and then
running on red hat linux 8 that causes the perverse line refreshes.
I figure this falls in the category of "don't do that!"

Anyways now we know a little more about readline in case the perverse
line refreshes ever strike anyone else.

Feeling bashful,
