Strange problem building Package commonc++

This is a multi-part message in MIME format.

Hi,

I have a problem building the package commonc++ for my custom target.

The target package selection is based on the tlx example and is very slim. It
is marked as a cross-build and targets x86 systems without any CPU-specific
optimizations. The target builds fine without commonc++. Now I have added
the package and the build fails at the make stage.

string.h? Feels pretty basic and I am sure the file in itself is OK. It is
even checked for while configuring:

config.log
(Complete file at: http://www.marian-aldenhoevel.de/tmp/config.log):

checking for string.h: yes
checking sys/un.h usability: yes
checking sys/un.h presence: yes
checking for sys/un.h: yes

What can cause this problem?

Ciao, MM
