Could you give some examples of these applications ?  I think that
this shows that making these libraries GPLv2-only at this stage may
have been a mistake.

for p in `apt-cache rdepends libgsl0ldbl`; do apt-cache depends $p |
grep -q libqt && echo $p; done

xorsa
snd-gtk
qtiplot
qgis
meep-mpi
meep
labplot
kwave
kst-plugins

those are applications linking to GPLv3+ libgsl and GPLv2 only libqt.

for p in `apt-cache rdepends libgmp3c2`; do apt-cache depends $p | grep
-q libqt && echo $p; done

ktorrent
klamav
kcalc
libcgal2
xorsa
regina-normal
qalculate-kde
ktorrent
klamav
kcalc
ihu

this is the same list for LGPLv3+ libgmp.  I don't know of other GPLv2
only libraries than Qt.
