ccache not yet supported?

I would love to see support for ccache in OpenTTD which is results with recent updated trunk (r19114) in non-working confgure and build steps. For example Speed-Dreams or UFO:AI, FlightGear and many other projects with the GNU make system work perfectly (Debian Unstable) with it.

ccache can be found here:
http://ccache.samba.org

As it claims for itself, it speeds up re-compiling nicely which is definedly true when you need to do a "make clean" to cleanup all objects (for what every strange linker/precompiler reasons).

To enable this feature, do the following before compiling (you need to "./configure --your-foo-params && make clean" for better testing):
export CC="ccache gcc"
export CXX="ccache g++"

If you want to make this permanently - wisely if you need to recompile often - add these two lines into your $HOME/.bashrc file and re-login.

Reported version: trunk
Operating system: Linux

Or they work nearly flawless, I didn't notice any problems with those games while compiling with ccache.

Hmmm, --with-ccache is there but it conflicts with the mentioned environment variables. A workaround is to add two lines just after the $id$ line:

unset CC
unset CXX

Which temporary removes the conflicting variables.

Edit: This is the problematic one. :)))

What exactly is the problem?
./configure --with-ccache enables ccache
You also mentioned the possibility of setting env variables.
