Hi all,

yes, I completely agree to Wayne's opinions. Especially the tons of \
compiler features turned _off_ by the default ./configure will -from my \
point of view- break several projects. For example exceptions are just a \
standard (and very useful) C++ construct and they are used by plenty a lot \
of C++ developers as they can make life a lot easier. So the real question \
is: What do we need a very powerful and nice IDE for when the underlaying \
scripts simply ignore the project settings?

All that weren't that much of a big deal if the current KDevelop 1.4
distribution were some sort of first run beta test. But the problem is
that KDevelop 1.2 along with KDE1 worked _perfectly_ while the current
version introduces _external_ problems that really shouldn't be there.

Honestly, KDevelop is one of the best IDEs I've ever worked with and I
really don't understand why its outstanding quality has to suffer from
a set of external shell scripts... I'd be glad if somebody posted some
real good reasons for all these odd compiler switches, so that I can
revise my opinion and be happy with KDevelop 1.4 again.

BTW: Has anybody managed to create text translation files (*.pot) with
KDevelop yet? All I get is an empty (zero size) .po file but no .pot.
I just want to make sure that I didn't do anything harmful before posting
a bug report... :-)

Regards,
Juergen
