Hi Tobi,

thanks for your quick response and the patch!

I ran the testcase against r2117 and it looks good. Thanks.


Bootstrapping from SVN took me a moment and in the process I noticed two minor
issues. They do not prevent RRDtool from compiling/working, though:
 -  make distcheck doesn't seem to work
 -  /configure: line 12300: ./libtool: No such file or directory


The latter is probably caused by this:

--- snip ---
~/tmp/rrdtool-1.4-r2117> cat ./configure.ac
[...]
dnl add pic flag in any case this makes sure all our code is relocatable
eval `./libtool --config | grep pic_flag`
CFLAGS="$CFLAGS $pic_flag"
--- snap ---

./libtool is present after 'make dist' but apparently not (always?) before.


The former yields this error message:

--- snip ---
~/tmp/rrdtool-1.4-r2117> ./configure && make distcheck
