I guess I have finaly found my preferred IDE for Atari cross development on the PC: Qt Creator.
It's pretty easy to adapt it to m68k-atari-mint Makefile-driven projects, it supports proper syntax highlighting, code completion, VCS integration, refactoring and context help. I even managed to convert a (slightly modified) toshyp download into a .qch help file:
Here I positioned the cursor on the rsrc_gaddr() symbol in the source editor window and hit F1 which popped up the help window with the toshyp documentation of that function.
With a proper project and Makefile definition, you just need to press Ctrl-B to build your project and Ctrl-R to fire up hatari with your program autostarting.
Atari cross development was never easier.
Most of my projects on Atariforge already contain proper QtCreator integration (but still can be compiled "traditionally" from a shell prompt). I can upload toshyp.qch (the help file for QtCreator) if anybody wants it. It should work on all platforms that QtCreator supports (Linux and Mac OS X tested).
