The current gdc supports d version 1.x.  The example you're doing, I believe, is for an alpha version of d (version 2.x).  const(char) and various const/final/invariant stuff was added in 2.x (and is the reason for the version # increase and calling it an alpha release)

the string alias was added in dmd 1.016 (which btw was a horrible idea imho), and with gdc 0.23 being 1.007 it's not availble, seems like someone was a bit enthusiastic updating the wikipedia pages.

OK, thanks. Does anyone knows when gdc will have D2.0?

You can get "string" alias before D 2.0, though ? It came
in DMD 1.016 and the GDC svn is currently up to DMD 1.020...

David Friedman hasn't published any E.T.A. on GDC 2.0 yet.
Could be since we haven't reached GDC 1.0 yet, but anyway. :)

Thanks, got svn gdc and it works. Just one thing: gdc --version still says it is synced to DMC 1.007, which is a bit confusing...

Indeed (that was true for GDC 0.23) It probably just hasn't been updated
yet, but should be before release (was wrong in a previous GDC version*)

You can enter a bug for it in Bugzilla perhaps, unless it's updated soon
Usually one can go off the ChangeLog, where it says "Merge DMD X.YYY"...

perl -pe 's@using dmd 0.149@using dmd 0.157@' -i d/gdc-version; \
