One wag once said something similar about a CPU design project I was 
one. Paraphrasing: Just let some VP file a bug report that says: 
"Product XXX does not exist". Then we can just keep amending that one 
until we close it.  That will greatly simplify having to remember 
various bug reference numbers.

Yes, well.  Been there a number of times, too.  As to the multiple OS 
issue, I'd say just pick one and then trust the ./configure stuff to 
make the rest work and just spot check them.

The graphical output part is always nasty.  Back when I managed a 
validation lab that Windows GUI software came through, we had a tool 
that did two things.  1. It intercepted the Windows API calls and 
allowed you to check expected values for window decorations and widget 
contents.  ie: Did a window titled "Foo Editor" just pop up?  Does it 
have a button named "Close"?, etc.  It also allowed you to script in 
clicks and such forth so you could automated driving the GUI around.  It 
was a darn tedious tool to use.  2. The other major feature was a 
pixel-XOR for selected windows.  This was problematic, in that any 
changes caused a fail.  You could specify regions (simple rectangles, I 
think) to be ignored.  Anyway, that about exhausts my memory of the tool 
-- I was in a pointy-hair position at the time and didn't actually spend 
any time driving the tool.

It strikes me that now that gerbv has a library with a nice API, we 
could do something like a pixel-XOR tool.  It's a pretty crude way to 
check GUI programs, but for simple test cases it may suffice.  Doesn't 
do much for screen comparisons, though.
