#26 configure problem detecting QT >= 2.1.0

[Peter Davis]

The configure script distributed with xIrc 2.3.8 does not detect that I have QT >= 2.1.0 on my
Debian unstable system. The line causing problems is at line 2586 of the distributed configure
script, where it says:

if test -r $QTDIR/include/qinputdialog.h; then

On my debian installation of QT 3, qinputdialog.h is actually located in
/usr/include/qt/qinputdialog.h. So the test fails, claiming that I don't have QT >= 2.1.0.

When I replaced the test with:

if true; then

then configure proceeded normally, and I was able to build and run xIrc perfectly. So it
appears that the only place $QTDIR/include is incorrectly hardcoded is in that section of the
configure script. Note that I also had to hack the configure script in the libX++ directory.
