Bug 67746

Confirmed. It appears someone forgot to implement it... :)

*** Bug 71561 has been marked as a duplicate of this bug. ***

This is a regression from KDevelop 2.x

This still happens in kdevelop 3.0.3 under linux 2.6.4 gentoo amd64.  It
doesn't just affect config.h either, it also effects the output file name
and output file contents of 'make dist'.

Even in KDevelop 3.0.4 it still here.

I'm obligated to find/replace (thank you KFindReplace) all version number by hand.

So, start a new project, and give it an unprobable version number (like "FooX452..bar;G" :-) ) and use KFindReplace to find all occurences, and be asured KDevelop update all those files when version number is changed.
With this process we could be sure the version will be REALLY changed.

My 1 cent.

Basicaly it only needs to change configure.in.in (In autotools based projects)
In other project types I'm not sure :(

Bug stil in kdevelop version 3.3.3.

When project/options/version is changed, update the configure.in file with the new version. 
Uses regex to update AC_INIT, AM_INIT_AUTOMAKE, and AC_DEFINE macros.
Build tools detect that configure.in is newer and rebuilds config.h with correct version.

Fixed in KDevelop 3.4 by revision 599871

Actually fixed in KDevelop 3.4 by revision 601133. 
I didn't notice this bug talking about configure.in.in. KDE use this to make the configure.in file. We now check for configure.in.in, configure.in and configure.ac and change the version.
