KDE2 development under KDE1 (not the standard question :-) )

[tom.verbeure at chello.be]

Hello Walter,

Errrr. Hum. You were right.
The fact is: I was fully aware of that config.cache could create
problems, because the first time after I patched acinclude.m4, my patch
didn't work due to config.cache. So I deleted it, reran configure and
then it worked, not because my patch solved it, but because it had to
work anyway. :-]

Well, in any case I am starting to figure out this whole configure
stuff. What is the best way to really that a grip on this? Do you just
fire up 'info' and read the whole manual or are there less painfull ways
to learn to use it?

Thanks,
Tom
