I have to admit I don't know GPL v1 too much

Hi Boris,
you *CAN* use open source software with closed source application.
The exception is when you're changing the source of the open
source application, which means you'll need to give back the
modification. I think linking to a FOSS product (GPL'd) is a bit
more problematic, but for this you can write some simple wrappers.
A wrapper would still be a problem as the wrapper would also have to be GPL.
IANAL but I think that an exception may be if you use the GPLed library as a
sort of plugin that can be fulfilled also by other libraries. For example you
can implement a simple inefficient proprietary library and a wrapper that allows
using the GPLed one as well and then you are easier of with your claim.
One of the reasons that a lot of major libraries (at least those that interest
me) us the LGPL to bypass this problem. Personally I try to stick to using
LGPLed software to avoid any issues.
In any case, if you distribute a (L)GPLed library you need to distribute the
source to that in any case.
You are wrong. Every distribution triggers the GPL. Changed source
code or not does not make any difference and linking to a GPLed
library usually (some exceptions apply) triggers the GPL if you are
actually distributing the library.
I've worked with some companies that linked/used GPLed software and also
followed some of these arguments previously. Which way dynamic linking goes is a
debatable issue (whether it can be considered derived work or not) and the
subject of many a flame war. It's never been tested in court though (neither
linking nor direct violation) so there is no precedence whether the GPL can be
enforced.
