Some of the tests have just been added the last few days! ;-) They are in SVN
now.

What version are you using? Released or SVN?

Unfortuantely, I don't know the name of this package in every distributions.
And what about Linux From Scratch? There's no package name there.

Is there an executable (or at least a file) that I can check the presence of
to say that libstdc++-dev is present? Will the same happen for, say, lic6-dev?

Now checked for by ./configure.

Ditto.

Yep. Heuristic is that if the source directory is present, then sources where
extracted and patched. Unfortunately, if some thing fails when extracting or
patching as you found, heuristic is broken.

Ah! Will add those two. Thanks!

Now checked for by ./configure.

Now checked by ./configure.

Would you consider testing the SVN trunk, please?

Yes! Definitely! Thank you!

Detection can be done. But a little text saying that some common packages
ought to be present can be added, yes. Will do that later today.
